High yielding seeds,
water and good fertile soil the three principal imperatives for agriculture. The rests are necessary
either to enhance efficiency of the operation or protect the crops being
produced.
Great strides have
been made in developing high yielding disease resistant hybrid seeds. Waters saving micro-irrigation technologies
have been developed. But when soil
fertility or plant nutrition is concerned, the pendulum on whether or not to use
mineral fertilizers keeps swinging.
Going organic is a
good proposition but the question is whether we can supply all the nutrients requirement of crops with organic manures to produce profitable economic yield.
Unless a farmer harvests a profitable
economic yield, proposing youths to take up farming is a defeating
proposition.
Different soils have
different capacity to supply plant nutrients to crops being grown.
When a crop is harvested, varying amounts of major nutrient elements and micro-nutrients are removed from the soil.
When a rice yield of 8 Mt is harvested from
one hectare land, it removes 152 kg Nitrogen, 37 kg Phosphorus, and 270 Kg Potassium.
Similarly, when a maize yield of 9.5 Mt is
harvested, it removes 150 Kg Nitrogen, 27 Kg Phosphorus, and 37 Kg Potassium.
Besides micro-nutrients including Sulfur,
Calcium, Magnesium, Iron, Manganese, Copper, Cobalt, Zinc, Molybdenum, Boron,
Silicon, Sodium and Chlorine, are also removed.
Any
of the plant nutrients either major or micro, becomes a yield limiting
factor if the soil is not able to supply the full amount required by the crop. This was declared by Justus von
Liebig in his books published in 1840 and 1855 declaring the Law of Minimum.
It was declared with
a barrel concept demonstrating that whichever plant nutrient is minimum limits the
crop growth and yield.
For instance, Boron
is deficient in the soils of Bhutan where apple is grown and apple is sensitive to Boron
deficiency. Farmers
apply Borax to apple trees to meet the requirement of Boron. Because Boron is not there in the local soils, it is also not there in the organic manures also. For this reason, applying organic manures to apple trees does not solve the problem of Boron deficiency.
Such micro
nutrient deficiency cannot be corrected otherwise and therefore must be applied
through external source.
Just as apple is
sensitive to Boron deficiency, mandarin orange is sensitive to Zinc deficiency. Similarly, cauliflower is sensitive to Molybdenum
deficiency and that is exactly the reason the cauliflower heads are much
smaller than they would have been.
Similarly different crops are sensitive to different micro nutrients
deficiency. To correct such micro nutrients deficiency applying micro-nutrients to horticultural crops is important. It will enable farmers to produce more and earn more income.
Applying micro-nutrients to crop makes fruits and vegetables in particular more nutritive and have no negative impact to environment.
The question is does all the soils have the capacity to sustain the supply of required amount
of plant nutrients to enable the farmers to harvest high economic yield years
after years. The answer is not. If it is not, the farmers
have to apply the additional supply from organic manure produced within the farm and from external sources.
Meeting the
additional requirement of plant nutrients along with organic manure is undoubtedly a
sound proposition. But on an average the
cow manure contains 0.6% Nitrogen, 0.4% Phosphorus and 0.5% Potassium.
The
chicken manure contains 1.1% Nitrogen, 0.8% Phosphorus and 0.5% Potassium.
The question is then; would the farmers be able to produce huge amount of organic manure to meet all the nutrients requirements, both major and micro-nutrients, particularly
the major nutrients which are required in large amount?
Applying mineral based synthetic fertilizers does not
outright pollute the environment or negatively impact human health.
The question is how we apply and how much we
apply matters.
The best answer is to apply
synthetic fertilizers judiciously and in integrated manner based soil test results and available
organic manure.
Maintaining soil
health is as good as maintaining human health.
Testing soil to decide how much fertilizers and /or manure to apply is
same as the medical doctors examining the patient and prescribing the
medicine.
Soil testing is yet to be part of agricultural practice in Bhutan. It is unheard by the farmers about its importance and implication in crop production.
Growing crops continuously without letting the soil to regain its plant nutrients supplying capacity naturally or without fully replenishing plant nutrients removed by successive crop has led to
low crop yield and soil
degradation.
Without full replenishment of plant nutrients being removed with every crop harvest, farmers cannot continue to harvest high
economic yield for ever.
Synthetic fertilizers,
when used judiciously along with organic manures in an integrated manner, help farmers to harvest high economic without posing
environmental or human health concern.
But
prices of fertilizers in Bhutan is prohibitive which increases the cost of production and reduce the
profit margin.
The price of fertilizers in Bhutan
is more than 100% compared to price across
the border in India.
For instance the
cost one bag (50 kg) of Urea or SSP is just over Rs 400/= in India, while price
of same stuff in Bhutan is Nu 895/=.
High cost of fertilizers and similarly all other agricultural inputs increases the cost of production
and the Bhutanese farmers loses the competitiveness against the Indian farmers.
In India from where fertilizers are brought, just as the LPG gas, fertilizers are also subsidized and controlled items. Ever since LPG sales is done by private sector, while fertilizer purchase and sale is done by
civil service agency.
The causes of huge price difference between that is India and in Bhutan remains mysterious. Could the difference triggered by subsidy factor, GST factor or some other unknown factor, which are never understood.
Subsidy on
fertilizers has always been a hard choice to agriculture policy makers.
During 1971 to 1981, agricultural growth in Asia has been much higher (19.6%)
with subsidy in fertilizers and less (10.2%) without subsidy.
In all developed and
developing countries, providing subsidy to agriculture is a common
practice.
The level of subsidy in
developed countries is much more greater than in developing countries, and the form
in which it is provided differs.
Generally in developed countries the products are subsidized while in
developing countries inputs are subsidized.
In the annual budget of India for 1015-16 the amount of subsidy for
fertilizers alone is Rs. 73,500 crores (73.5 billions).
Historically,
agricultural subsidies have dominated the agricultural policy agenda in all
economies -developed, developing and transitional. In developed countries the subsidies have
been mostly in the form of price support for both domestic and exports.
Unlike the developed
countries, developing countries have relied more heavily on input subsidies. Fertilizer subsidies became popular for both
political and economic reasons. Politically,
they became an instrument of pleasing farmers in the rural sector, and
economically, the benefits out-weighted the cost of fertilizer subsidies.
So long the benefits
outweighs the cost of subsidy, the economist and policy makers should willingly
support. After all the WTO too under the Agreement
on Agriculture (AoA) allows subsidy (up to 10% of the Agriculture GDP).
The economic and
social benefits of subsidizing fertilizers and their assumed negative impact,
which results only from excessive use and misuse, are least researched. The policy is being framed either only on political reason or on misinformed
information or both and this has been the cradle of problems.
Also the move for going
organic looming large not letting to practice balanced crop nutrients
management and therefore starving crops for want of adequate major and micro-nutrients for
producing economic yield. Not
using or applying micro-nutrients like Sulfur, Zinc, Boron Molybdenum, Calcium
or Iron, which are needed by plants just as human being, is limiting yield of different crops.
The first step
towards going organic is reducing the current level of use of fertilizers and conversely using them judiciously. The technology available for reducing the use
of fertilizers in vegetables and fruit crops is being left to take up on its
own.
The drip irrigation to which the
fertigation technology is integrated delivers plant
to the roots of the crops only just as life saving
liquid is injected to seriously ill patients in hospitals. But the dilemma is that neither drip irrigation system with fertigation option nor plant
nutrients have received due attention.
Since drip irrigation saves water op to 70%, with same amount of water vegetables and other dry land crops can be grown during winter and spring months in mid altitude and low altitude ares which otherwise considered impossible.
Drip irrigation provides solution to revive the citrus industry and in achieving vegetables self sufficiency yet there is no prescribed investment support
for promoting drip irrigation.
With drip irrigation along with fertigation there is a scope of saving 90% Urea (Nitrogen:
-fertilizer), 80% MOP (Potassium: -fertilizer) and 45% SSP/DAP (Phosphorus:
-fertilizers) currently being used for vegetables. This will be a quantum
leap towards going organic.
Indian agriculture
policy is probably the best among developing nations which subsidizes production
technologies like green house, drip irrigation and others by both central
government and state governments. The
extents are up to 25% by central government and 50% by state governments. Besides in state like Punjab the government
gives free electricity if a farmer goes for drip irrigation in large
scale. It is true that the subsidies are
often given for political reason but it cannot shadow the economic reason for the
purpose of diversifying production, import substitution, saving water, and
reducing the use of synthetic fertilizers.
In Bhutan practicing
green house production is the most expensive proposition. The primary cost of green house as such is
high and to the base price 30% tax (custom duty and sales tax) is levied if
imported from third country and 10% if imported from India. The poly film needs to be replaced on a
regular interval and to the poly film alone when imported, 40% tax is levies. This is the scenario against up to 75% subsidy being
given in India on protected cultivation.
It is true that the
issue of agricultural input subsidy and support mechanism are complex. But we have huge institutional set up where
large number of well qualified researchers are working who can do much needed
policy research. It is impending as more
than ever the policy makers need guidance on how to resolve the possible
conflicts between the need to encourage farmers to increase agricultural
production realizing agriculture as a profitable enterprise and the hosts of
issue including tax on production technologies and inputs, removing or not
providing subsidies to high yielding hybrid seeds, green house, drip irrigation
and similar others and going organic on its own right.
In Asia region, the
country like Singapore which has over 6 millions population does not have villages,
farms or rural societies, and imports all its foods. It imports basic items from neighboring
countries like Malaysia or Thailand, where the private sector of Singapore is
engaged with local private sector. The
food standards are very high and so is production processes. The production process for examples in
Northern Thailand does not bar use of fertilizers. Whatever plant nutrients are needed by the plants
to produce high economic yield is provided to the plants in a manner that does
not exceed the limit and standards so as to produce healthy food for healthy
human health.
Three things: good human health, serine environment, and high economic return, are the production
principles pursued by Singaporean investors.
We too should actually aim at. To
achieve these three, we need wisdom and skills.
Due to high input
costs, the Bhutanese farmers lose competitiveness against their fellow counterparts
across the border in India. For instance
the potato farmers across the border buy 50 kg SSP fertilizer bag at Rs 400/= per bag
while Bhutanese farmers buy the same bag at Nu 895/= per bag.
The Indian farmers across the border do not
use herbicide for simple reason that potato is grown after rice and therefore
the weed pressure is low. The Bhutanese
farmers use very expensive herbicide called Metribuzin, and Glyphosate banned in many countries, to control weeds in
their potato crop.
In spite of all, the average yield
of potato in Bhutan is around 15 Mt per hectare where there is more than
six month growing period, while across the border the Indian farmers harvest 30
Mt per hectare where the growing period is just over 3 months (90 to 100 days).
It is not only high
labor cost but the hosts of high input costs increases the production
cost of Bhutanese farmers.
Low profitability of
Bhutanese agriculture is mainly due to high input cost which is responsible for
high prices of local produce. It poses
dilemma that rising urban population want cheap food as they spend substantial
portion of their income on food.
The question with
regards to high input cost is; should farmers alone be forced to bear the cost,
when society-at-large benefits from increased production, lower food prices,
and a sustainable natural resource base.
If Bhutanese farming
has to sustain rural livelihood and provide employment opportunity to job
seeking youths, the only option is to bring down the spiraling input costs.
The cost of
fertilizers can be immediately brought down if fertilizers are grouped with LPG
gas and imported in the same manner as LPG gas is imported MOEA at a subsidized cost,
subsidized by the Government of India. And
by letting private sector to transport, distribute and sale just as LPG gas, the
civil service agencies currently buying and selling fertilizers will be freed to do important development works. In no countries in the world buying and selling of seeds,
fertilizers, pesticides and other agricultural inputs is
done by civil service agencies and there is no reason to be different.
Buying and selling hybrid
vegetables seeds is just as buying and selling cars. Different
companies have different branded and patented products. The product is continuously upgraded, and
hybrid seeds cannot be reproduced. If buying
and selling of notified hybrid vegetables seeds is deregulated to private sector,
the private sector entities competing in the market would supply more efficiently. And the civil service agency involved in
importing / purchasing and selling hybrid vegetables seeds upon adding profit could be meaningfully
engaged in producing, supplying seeds of food crops such as rice, maize and others, supporting the goal of food self sufficiency.
High cost of
production technologies like green house could be reduced straightway by 30% by
removing the custom duty and sales tax.
Subsidy on drip
irrigation is genuinely justified for it increases production, saves water and
reduces the use of fertilizers and promotes organic practices.
Reducing the use of
fertilizers is the first step towards organic farming. Most SSP, the phosphorus containing fertilizer is used by potato farmers. Most Urea, nitrogen fertilizer is used by maize farmers of eastern Dzongkhags. Currently around 3000 mt fertilizers are imported annually. It is important that how we can bring down its price and use them most judiciously for maximum benefit and minimum impact.
The farmers of western
dzongkhags use the herbicide Butachlor (5% granules) to control weeds in rice for which around 400
Mt is imported annually. ver since Butachlor 5% granules was introduced in early 1980s no alternative has been found till date and no herbicide is promoted for controlling Sochum weed in rice for which farmers spend as high as Nu. 15000 per acre to control this weed.
The objective of agriculture has been to increase production but little attention is given in bringing down the cost of inputs which increases the income / profit even when the crop yield is not increased.
The other pivotal area which have to be focused and supported is the cooperative marketing, a topic that warrants separate article.
