How to build soil crumb structure by yourself?

图片
The main measures to build soil crumb structure 1,Intensive cultivation,increase use of  organic fertilizer Intensive cultivation makes the topsoil loose.Although the formed granules are not water-stable,they also play a role in regulating soil porosity.The continuous application of organic fertilizer can promote the formation of water-stable aggregates,and the degree of agglomeration of aggregates is high,various pores are distributed reasonably,and soil and fertilizer can be maintained and improved. 2,Rational rotation Annual or perennial grasses or leguminous crops,which grow robustly and have developed strong root systems,can promote the formation of soil aggregates.Returning straw,planting green manure,crops and green manure rotation,and paddy crop rotation are all beneficial to the formation of soil crumb structure. 3,Reasonable irrigation,timely cultivation Flood irrigation can easily damage the soil structure,so that the soil is compacted,an...

What’s the Crumb structure in soil?

图片
First of all,let us understand the soil structure. The soil is a porous system.It consists of solid,liquid and gas three-phase substances.The solid material in the soil includes both mineral and organic matter.The liquid part refers to the moisture of the soil,which is preserved and moved between the pores of the soil and is the most active part of the soil. The gas part refers to the air of the soil and it is filled with pores that are not occupied by moisture.The pores are divided into three types: large,medium,and small.Among them,the large pores are called gas-filled pores.Large pores should not be too much,water is easy to run off if too much,and the pore size of small pores is too small,which is not conducive to the breathability and rooting of plants. Medium pores are also called water-holding pores.The more midium pores are more suitable for the growth of crops.Just like our human skin,the better the water retention and air permeability,the healthier it is. Crumb struc...

How Bacillus mucilaginosus can Prevent drought in the summer?

图片
When it comes to drought prevention ,everyone thinks that they may need more watering.Now,there is a better way that we can use microbiological fertilizers like Bacillus mucilaginosus to prevent drought. The reason is that:Bacillus mucilaginosus is also called silicate bacteria,it has strong potassium-dissolving ability,which is selected from the roots of crops and produced by industrial fermentation with a specific medium.Through its life activities in the soil,it increases the supply of plant nutrient elements,stimulates crop growth,inhibits harmful microbial activity,and has a strong effect of increasing production.It is currently the most significant and widely recognized microbial agent. Bacillus mucilaginosus 1.Bacillus mucilaginosus can secrete plant growth regulators such as auxin and gibberellin,increase roots and make seedlings strong,and directly enhance drought resistance of plants. There are auxin substances and gibberellin substances in the bacteria and ferm...

Case of Dora Rootguard used on strawberry

Strawberry is a kind of berry that is very sweet and very popular amoung consumers.However,with the adjustment of agricultural planting structure,especially greenhouse planting in winter,the pests and diseases of strawberries have been aggravated.Strawberry growers generally reflect the serious phenomenon of strawberry death after planting. The reasons of these phenomenons  1.Continuous cropping Continuous cropping is a problem for strawberries and growers know it. So they use a lot of chemicals to treat the soil every year. At the same time,the beneficial organisms in soil also be killed. It lead to the situation that strawberry’s roots could not adapt quickly,even seedlings death. 2.Fertilization  If raw manure and unripe organic manure are applied and a large amount of water is poured after planting, it will lead to seedling/root burnt. Therefore, it is necessary to apply decomposed organic fertilizers as well as watering in advance. It is advisable ...

Soil acidification big disaster for crops and soil

 The main reason for soil acidification is the increase of hydrogen ions in the soil  Bio-solution to control soil acidification,please check  http://www.doraagri.com/product/dora-rootguard/ Precipitation is large and concentrated, leaching is strong, calcium, magnesium, potassium and other alkaline salt loss, is one of the reasons that cause soil acidification. The lack of traditional agricultural measures such as lime application, burning of fire excrement, and application of organic fertilizers has caused imbalance of nutrients in cultivated soil as one of the causes of soil acidification. Long-term large-scale application of chemical fertilizers, especially physiological acid salt is an important cause of soil acidification. Chemical fertilizers have been used for many years in succession. The acid radicals remaining after the crops absorbed combine with hydrogen ions in the soil to form acids, which can lead to soil compaction, increased acidity, and caus...

Why does crop quality decline after continuous cropping?

图片
In some plants,stems and leaves appear scorching and shrinking,and some even die.Some pest structures also change.This is what the performance of continuous cropping obstacle in different crops.  The reasons are generally the following aspects: 1.Continuous cropping causes symptoms of deficiency in soil Field crops have a long reproductive cycle.The vegetable has a short growing period and a high multiple cropping index. However,whether the same crop or vegetable is grown on the same land for a long or short period,it will absorb more elements, and the element in the soil will be in short supply.Some will also lead to changes in the pH of the soil,and the availability of certain elements in the soil will also decrease.As a result, some cotton will have potassium deficiency,some cabbage will have calcium deficiency, and some will suffer from Zinc Magnesium deficiency. 2.Serious harm of pests and Pathogens in soil The common diseases in continuous cropping fields a...
