Organic nutrients source for plants
Source of plant nutrients: The modern-day farmers are depended on high tech agriculture. They use various components of advance agriculture to get commercial successful in the field of farming or agribusiness. Commercial and regular cropping results in the rapid loss of soil fertility, that’s why farmers use a large amount of different fertilizers to meet the nutrients demand of the different crops.

(1). Why organic nutrients
1.1: Crop pattern
Monocropping is one of the biggest reason of soil fertility loss. For example, rice as a monocrop will exhaust all the available nutrients in soil year by year making the soil less fertile. In case of monocropping, organic matters are necessary to maintain the soil fertility without the use of chemical fertilizers.
1.2: Human health
Human health is greatly affected by its surrounding. Use of chemical fertilizers is increasing day by day to get more yield. This practice leads to the accumulation of chemical residues in soil. The soil is becoming today toxic and more toxic. A plant absorbs this toxic as its food. And, these toxic substances reach inside human body to cause severe health problems.
1.3: Soil health
Soil health is deteriorating very fast due to the excessive use of chemical fertilizers. Toxic soil, acidic soil, etc., are the major problems due to the regular use of chemical fertilizers. There is a direct connection of soil health with human health. We have to correct soil health by using organic soil amendments.
1.4: Microbial activities
Heavy dose of inorganic fertilizers may cause problems for various beneficial microorganisms. Organic matters such as farm yard manure, vermicompost, urigo, green manure, etc., directly support the activities of soil microorganisms.

- Farm yard manure.
- Green manure.
- River soil.
- City residues.

Vermiompost is an organic manure.
Scientific name: Eisenia fetida
Production of vermicompost
Buy HDPE vermibeds.
Make a shade-structure.
First layer: Agricultural organic waste.
Second layer: Cow dung
Third layer: Release earthworms.
Fourth layer: Cow dung.
2.2: Farm Yard Manure
Farm yard manure is an organic manure.
Preparation of farm yard manure
- Make a pit.
- The size of pit depends on your decision.
- Collect cow dung and agricultural waste (plant residues).
- Fill the pit gradually.
2.3: Green manure
Green manure is an organic matter.
It is undecomposed material.
Legume crops are best for G. M.
These are green manure crops.
Examples: Sunhemp, dhaincha, pillipesara, cluster bean and sesbania.
- Grow green manure crop.
- Collect green manure leaves.
Apart from green manure, sunhemp is also a fodder crop.
It a tropical plant.
Cluster is a vegetable as well as an excellent green manure.
All parts are used as green manure.
It is legume a crop. Sesbania is one of the easily available green manure crop. You can harvest it during rainy season. In many places, it is considered as weed. The plant is a shrub which has woody stem. It bears yellow flowers. Leaves, flowers, and tender parts are suitable for the preparation of green manure.
2.4: River soil
River soil is rich in organic deposits.
You can add river bed soil to your garden soil.
This article is talking about river bed soil, not about river sand.
2.5: City or urban residues
City or urban residues is the organic waste by cityzens.
Collect chemical free urban residues.
Mix it with soil to make it more productive.
