How to improve soil fertility

How to improve soil fertility - Land is an important role in improving agricultural yields, barren soil that does not have the quality of fertility for the survival of plants will certainly not good for applied in cultivation, some plants can easily adapt to certain land but also as a plant must be assisted in the process of forming humus so that the land is suitable for agricultural land, but also the land is a place of root growth, food storage, micro water storage and micro organisms and so forth that is good for plants.

Land that is often used as agricultural land especially vegetables with a certain period and the process of vegetable turnover periodically will decrease the level of soil fertility especially in the process of planting often use chemical fertilizers and pesticide drugs in the handling of pests will be very easy reduce the fertility of the soil.

There are some differences between soil fertility and soil health, soil fertility is the ability of the land that has a function to increase the growth of plants physically, and biology it has. While soil health is a soil condition that can support the growth of plants in a healthy manner without any disturbance.

These two elements can change due to several factors as I described above one of them:

1. Decreased soil fertility

The presence of nutrient absorption contained in a soil evaporation of nutrients into the atmosphere, absorption into the soil, and the occurrence of erosion.

2. Decrease of soil health

While other factors that influence the decline of soil health is due to the factor of the absence of gradual organic elements in the soil, the excessive use of chemical fertilizers that are given continuously, the presence of chemical contamination, and the existence of the process of burning on land, and erosion.

Some good and fertile soil elements usually contain some of the elements in which they are

A. The presence of valuable biota-biota ( microfauna, microflora, macrofauna ) is largely in it.

B. The existence of humus / flowering soil (made from broken and decomposed organic compost, compost, mulch, animal waste and others.

C. Have some sand and clay contents so that the soil function is balanced as a binder on minerals while sand serves as a possible draise.

D. Physically-visible plants grow easily on the soil.

E. The soil structure is clay textured, has good porosity and water sucking power.

F. Ph content contained in the soil is neutral.

soil fertility has an important role in planting crops, this kind of thing is not easy if we just leave it alone in the absence of certain processes so that the land has these elements, to improve the process effort there are special methods used in increasing fertility and soil health among them :

1. The Rest of the Land

Land that is often used for cultivation will decrease the 2 elements of soil health and soil fertility one that can be done to improve the element again that is by resting the soil by not in use the land for planting in a certain period of time.

2. Plastic Closure

This process is done by covering the soil surface with straw or dry twigs in the pile above the soil surface within a certain period of time this process serves as a deterrent in the loss of evaporation of water contained in the soil that can cause erosion and rainfall on the soil the.

In addition, the provision of these materials serves as a hindrance to the growth of weeds that are not good for plant growth when later in use again.

3. Give Organic Fertilizer

Provision of organic fertilizer we can use such as manure, green manure and liquid fertilizer. In fertilizers sometimes function as a fix the structure of the soil or improve the health of the soil, while the green manure which we mean here is we can planting plants containing various bacteria or substances that are good for soil fertility example is leguminose / creeping and covering the surface of the soil then buried into the ground with a plow or rake, for the liquid fertilizer we use here is a fertilizer that contains nutrients, cheaply making, increasing the number of biota and improve the quality of soil structure.

So how to improve soil fertility that can be used as a material to restore soil fertility, may be useful.
