Various measures of soil conservation Part II (1+1+1 System) Geography Hons. Paper: IV Module: VI Topic: 2.2 Soil conservation measures: Conservation and restoration of soil is necessary to protect our cultivated farms and expand available land for agriculture with a view to increasing food production for the future. Conservation measures must therefore fulfill the following objectives: (i) protection of the surface from the impact of raindrops, (ii) increase in rainwater infiltration, (iii) decrease in the volume and velocity of surface runoff, (iv) enhancement in soil resistance to erosion by judicious modification of the physical and chemical properties of soil ...
1 SOIL CONSERVATION Soil erosion in rubber plantations can be greater, which are situated on undulating to steep terrain with high intensity of rainfall, especially during the early years after planting. But at the same time soil erosion can be minimized to a great extent by proper soil conservation and must be ensured in order to preserve the productivity and fertility of the soils of rubber growing areas. METHODS OF SOIL CONSERVATION Whatever the method that may be employed, the following 4 aspects are involved in minimizing soil erosion. Improve the structure of soil, to make it resistant to detachment ...
CHAPTER 14 COMPOSTING 14.1 INTRODUCTION The organic content of Municipal Solid Waste (MSW) tends to decompose leading to various smell and odour problems. It also leads to pollution of the environment. To ensure a safe disposal of the MSW it is desirable to reduce its pollution potential and several processing methods are proposed for this purpose. Composting process is quite commonly used and results in production of a stable product - compost which depending upon its quality can be used as a low grade manure and soil conditioner. The process results in conservation of natural resources and is an ...
