Characteristics Of Fertilizers
- Oct 10, 2017 -

Fertilizer is the grain of the crop, is the material foundation of increasing production, our country awakening has "the farming not to be on the dung, equals blind hu Hun" the saying, according to the UN FAO statistics, fertilizer in the grain increases the function, including when the season effect and the aftereffect, Fertilizer the average increase in yield is 50%, our country recent years soil fertility monitoring result The contribution rate of fertilizer to the yield of agricultural products is 57.8% nationwide average. China's 7% of the world's arable land, which feeds 22% of the world's population, owes half of its contribution to fertiliser.

We can provide nutrients to plants by applying them to the soil or by other means, or to improve the physical and chemical properties of the soil, to provide a good living environment for plants collectively referred to as fertilizer.

At present, there are still many problems in the application of fertilizers, such as heavy fertilizer, light organic fertilizer, heavy nitrogenous fertilizer, light phosphorus, potash fertilizer, neglecting micro-fertilizer, heavy yield, light quality and outdated application method. There are many undesirable consequences: first, the decline of land force, the impact of sustainable development of agriculture, the second is the low utilization of fertilizer, waste serious, pollution of the environment and groundwater; third, high cost, low efficiency, Fertilizer slow and even stagnant agricultural income; Facing the development of "three high and excellent" and advocating the new situation of agricultural sustainable development, Fertilizer guiding the broad masses of rural cadres and farmers to renew their ideas, and reversing the tendency of "triple three light", adjust the fertilizer structure, implement the measurement, distribution, production, supply and application integration, has become the focus of current fertilizer

Fertilizers are chemical methods of making or mining ores, after processing of fertilizer, also known as inorganic, including nitrogenous fertilizer, phosphate fertilizer, potash, micro-fertilizer, compound fertilizers, and so on, they have the following common characteristics: simple ingredients, high nutrient content, fertilizer efficiency is quick, fat vigor; some fertilizers have acid-base reactions; No change in soil fertility. There are many kinds of fertilizers, Fertilizer and the properties and application methods differ greatly.

Fertilizer characteristics: The characteristics of fertilizer itself and the rational distribution of nitrogenous fertilizer is closely related, ammonium nitrogen fertilizer table is easy to volatile, it is advisable to do the basal soil. The nitrate nitrogen fertilizer has strong mobility, it is unfavorable to make basal fertilizer, Fertilizer it is unfavorable to apply in paddy field. Ammonium, ammonia, urea, ammonium nitrate is not generally suitable for seed fertilizer, ammonium chloride should not be applied in saline-alkali soil and low-lying land, but also suitable for cotton, tobacco, sugar cane, potatoes, grapes, sugar beet and other chlorine-repellent crops. Nitrate nitrogenous fertilizer should be distributed in arid area, and ammonium nitrogen fertilizer should be distributed in rainy area or rainy season.
