Some factors affecting agricultural production include:
Seed is one of the factors that influence agricultural production. These factors included that can be controlled. If we want a good seed, we simply buy in a store and choose a well tested. Although not 100% good, but so far we can still trust the seed issued by the state we are in the field of seed.
2. Pests and Diseases
Pests and diseases is one of the factors affecting agricultural output. These factors include factors which can be controlled, however sometimes this control is not entirely successful. Control is sometimes even cause the soil to be damaged.
3. Climate (including the adequacy of water)
Climate is one factor that affects agricultural output that can not be controlled. However, we still can control (although not entirely) for example by making drainage, by holding the artificial rain and others.
4. Fertilizer given
Fertilizers are the factors that affect agricultural output, the most we can control. If you want high results, give it a good fertilizer at its optimum.
5. Soil conditions
The soil is one factor that can affect agricultural output, and we can control, although not all of them. The soil is often poorly understood by farmers and agricultural extension workers, although this includes a very important factor, as it relates to factors of fertilizer.
The problems facing farmers today is the decline in productivity. Over the years we tend to see the productivity of rice has decreased. Even though given excessive amounts of fertilizer, production remained constant, even tends to fall. Dose of fertilizer now tend to be very high. Farmers have not had enough if not given as much as 1 ton of fertilizer per hectare.
The problems mentioned above due to soil conditions are not favorable right now, namely because it is too acidic (a result of excessive chemical fertilizers and continuous), reduced soil micro-organisms and microbes.
It is well known that the addition of chemical fertilizer is continuously may cause damage to soil structure and death of some microbes and microorganisms in the soil. One function is to decompose microorganisms (outline) so easily consumed nutrients plants. Some microbes (such as rhizobium) can even capture Nitrogen (N) are free of air to consume the plants. Whereas approximately 70% of our air consists of nitrogen. Some others (like Michoriza), capable of capturing P not available for plants become available. If micro-organisms and microbial plant is very less in number in the soil, it can be predicted that the consumption of fertilizer will be very high with very poor results.
EFFORTS TO INCREASE PRODUCTION
Once we know the existence of micro-organisms and microbial factors are very less, therefore the proper treatment, which improve soil structure and adding soil microbes.
Currently, the efforts made by farmers are often less on target. For example, to reduce the acidic nature, given secra excess lime plants, whereas limestone itself contains elements of a very high Ca. In addition, farmers also often add compost to improve soil nutrients. Compost is good, but on condition that a little soil microbes, the compost is only a little effect on the plant.
Increasing acidity by providing zeolite (and a little lime). During this zeolite known for their ability to increase soil pH, without side effects. Because of the increased soil pH by releasing ions easily separated, yaiti Al2O3 and SiO2 and exchanged with acid elements. The elements released by the zeolite is not / less absorbed by plants.
After the pH rises (more neutral conditions), then the second is to add fertilizer containing microbes (such as rhizobium, mychorizae or Azotobacter). Rhizobium is a bacterium / microbe that mampun absorb N from the air, while mychorizae and Azotobacter bacteria that can absorb P not available becomes available. Both bacteria (rhizobium and Azotobacter) can live and multiply when it finds a host, the plant roots. So giving these bacteria should be on when the plants are young (sat on a seeding or planting at the field). Currently, the provision of this bacterium is still limited to crops. However, the author never tried this applied ditanaman cereals, and it worked.
After giving the microbes, then the next is to provide manure compost. Compost serves as a provider of food for bacteria, and also for plants.
The existence of the three above treatments will lead to reduced consumption of chemical fertilizers. Even in year two the number of chemical fertilizer can be reduced by 50%. While the provision of microbes and the compost can be reduced gradually.
