<h2>Background:</h2>
<ul>
<li>Intensification of cropping systems and adoption of modern agrotechnologies
have caused a continuous decline in soil fertility leading to low yields and
unsustainability </li>
<li>Balanced fertilization is the only way to bridge the gap between nutrient
supply by the soil and crops uptake, in order to sustain productivity in modern
farming without deteriorating soil health </li>
</ul>
<h2>Objectives:</h2>
<ul>
<li>To study the effect of nutrient management on the productivity and sustainability
of a sorghum-wheat intensive farming on a long term basis</li>
<li>To study the long-term soil fertility management through balanced plant
nutrient supply, with emphasis on POTASSIUM</li>
</ul>
