3. INTRODUCTION
Integrated Nutrient Management is a practice where all source of
Nutrient namely organic, inorganic (chemical fertilizer),bio-fertilizer can
Be combined use for improving soil health , get good quality yield and
Maintain ecology and environment.
The continuous and imbalance use of fertilizer is adversely affecting the
Sustainability of agriculture production beside causing environment
Pollution. the major issue for the sustainable agricultural production
Will be management of soil organic carbon and rational use of organic
Input such as animal manure ,crop residues ,green manure know as
Integrated plant resources management. However , since organic manure
Cannot meet the total nutrient needs of modern agriculture.

4. PRINCIPLES OF INM
►Maximize the use of organic materials
►Ensure access to inorganic fertilizers and improve the
efficiency of it’s use
►Minimize losses the plant nutrients

6. ► To increase the availability of nutrients from all sources in the soil during growing session.
► To match the crop demand for nutrients, with the capacity of soil to meet this demand plus the
external sources of nutrient supply.
► To optimize various soil biota interaction.
► To minimize the loss of nutrients in the soil and also the harmful effects of chemical fertilizers
on the soil health .

7. COMPONENT OF INM
• Chemical fertilizer
• Organic manure
• Bio-fertilizer
• Green manure

11. Type of Manure
On the basic of concentration of nutrients, manure can be grouped in to two
1. Bulky organic manure
In this manure are contain small percentage of nutrient and they are applied in large
quantities.
FYM, compost and green manure are the most important and widely used in cole crop.
FYM
FYM contain 0.5 % N, 0.2% P, 0.5% K one tone of cattle dung can supply only 2.95kg N ,
1.59kg P, 2.95kg K.
Compost-
compost contain .5%N, .15%P, 1.4%K.
Green Manure
