What do you need to pay attention to when topdressing with organic fertilizer?

How to top crops with organic fertilizer? What problems should organic fertilizer topdressing pay attention to? The following farming network for a brief introduction, for netizens reference. 1, early chase: organic fertilizer contains quick-acting nutrients, but the amount is limited, the release of a large number of slow-acting nutrients requires a certain process, organic fertilizer should be a few days in advance when topdressing. 2, topdressing high-quality organic fertilizer: during the rapid growth of crops need a lot of nitrogen and potassium and other nutrients, general organic fertilizer nitrogen and potassium nutrient content is not high, in order to ensure the rapid growth of crops on the nutrient demand, to choose high-quality organic fertilizer with high nitrogen and potassium nutrient content. 3, the development of a reasonable proportion of base fertilizer allocation: such as low ground temperature, microbial activity is weak, organic fertilizer nutrient release is slow, most of the amount of application can be applied as base fertilizer; and high ground temperature, microbial decomposition ability is strong, if the base fertilizer is too much, before planting, fertilizer is over-decomposed by microorganisms, after planting, immediately play fertilizer efficiency, sometimes may cause crop growth. Therefore, under high temperature conditions, it is best to reduce the amount of base fertilizer and increase the amount of topdressing. 4, seedling should be appropriate: crop seedlings need small amounts of nutrients, but insufficient nutrients can not form strong seedlings, which is not conducive to transplanting, but also not conducive to future crop growth. Fully decomposed organic fertilizer, uniform release of nutrients, nutrients comprehensive, is an ideal fertilizer for seedling. Generally, a certain amount of grass carbon, vermiculite or pearlite is added to the fully fermented organic fertilizer, and the soil is mixed evenly to make the seedling substrate. The amount of organic fertilizer should not exceed 10% of the total weight of the nutrient soil. The above is the notice of organic fertilizer topdressing on farming network.
