Soil erosion prevention practices such as this can drastically decrease negative effects associated with soil erosion such as These are: It is an easy way of measuring and mapping the surface of land. Supports Diverse Crops through an Adaptable System. Disadvantages: Can be dangerous if exposed to humans, creates pollution, and reduces nutrients in the soil. In addition to preserving the soil and preventing erosion, contour plowing/ploughing helps cut down fertilizer loss, as well as increasing crop yields by up By convex lenses?

Disadvantages:High soil moisture loss, destroys soil structure, compacts wet soil. Advantages and disadvantages of a contour map? Under strip-cropping conditions, alternate parcels of different crops are grown on the same field. Intercropping promotes synergistic interactions, which reduces the number of actions a farmer needs to take.

One major disadvantage of terracing is rainwater saturation of the ground. To accumulate moisture in these dry areas, cropland is periodically left fallow. They took hikes of increasing length for each of 4 days and rested on the fifth day. The strips with the greatest surface vegetative cover capture soil eroded from upslope areas.

This happens when terracing retains too much water, which is absorbed into the ground. well all i have to say for now is hino college boys ask ur parents. Contour farming can also reduce soil erosion by as much as 50% compared to farming up and down hills, according the Natural Resources Conservation Service. Soil Conservation Service to promote contouring in the 1930s as an essential part of erosion control eventually led to its widespread adoption. Some advantages of contour plowing is that it focuses on preserving topsoil by reducing erosion from water runoff. To fulfill the food and fiber needs of the people while enhancing the soil, limiting the use of nonrenewable resources, and allowing for economic viability for the farmer. Slugs, earwigs, cutworms, and other pests love cool, dark, moist places. Because mulch blocks sunlight, it prevents some seeds from germinating. This can end up causing more damaging runoff than in unterraced areas. The advantages, other than these being farm machine friendly, are enumerated in this chapter (under cut-and-carry systems).

C) The sounds frequency decreases. In alternating strips of productive and non-productive species, nutrient gains are often coupled with some form of insect control, e.g., repellant plant. WebContour ploughing helps to reduce soil erosion . Because of this, farmland stays fertile much longer. Intercropping gives additional yield income/unit area than sole cropping.
