How do you clear a planting field?

Clearing a Field or Land for Crops

  1. The first job is to cut brush and small trees back to the fence line.
  2. Using a heavy-duty pair of lopping shears, cut small growth straight across and as close to the ground as possible.

How do farmers prepare land?

First, you need to clear the field from weeds, then systematically arrange the field in a way of leveling the field, setting up channels and roads. Deep soil tillage should be done in summer or early autumn. It implies flowing in greater depth, undermining, vertically deep loosening or mole drainage.

Why do farmers prepare their agricultural land?

Land preparation improves site conditions in one or more of the following ways: Reducing weed competition for light and nutrients. Improving soil, water, and air conditions through & water cultivation. Loosening tight or compacted soils to allow.

What are the 4 stages of plant growth?

Basic Facts

  • The average plant goes through four stages: seed, sprout, seedling, adult plant.
  • Seed. Through pollination (pollen reaches the stigma) and ferilization (the pollen and stigma join), a seed is formed.
  • Sprout. The next stage, the sprout, is when the shoot reaches the surface.
  • Seedling.
  • Adult Plant.

How do farmers protect their crops?

Crop protection encompasses: Pesticide-based approaches such as herbicides, insecticides and fungicides. Biological pest control approaches such as cover crops, trap crops and beetle banks. Barrier-based approaches such as agrotextiles and bird netting.

Why are fertilizers bad?

Chemical fertilizers have aided farmers in increasing crop production since the 1930’s. Some of the harm chemical fertilizers may cause include waterway pollution, chemical burn to crops, increased air pollution, acidification of the soil and mineral depletion of the soil.

How does too much fertilizer affect plant growth?

Excess fertilizer alters the soil by creating too high of a salt concentration, and this can hurt beneficial soil microorganisms. Over- fertilization can lead to sudden plant growth with an insufficient root system to supply adequate water and nutrients to the plant.
