Alley cropping is a very useful technique for improving poor soils, providing fodder for animals and protecting the soil from heavy rainfall.
Alley growing is a simple way to combine trees and crops. Rows of suitable trees are planted at a distance of 5 meters between rows, usually sowing the soil directly at the beginning of the rainy season. Between the tree rows, crops or vegetables are planted as usual. On sloping soils, rows are planted along contours - across the slope. Alley cultivation can also offer some protection during uneven rainfall as tree rows help to hold down rain on the soil.

Plant cells and animal cells undergo the same cellular processes during mitosis.
The centrioles absent in the plant.
Animals cells have centrioles, to what delivers the shaft strands is one of the differences among plant and creature mitosis.
The periods of mitosis and goes on in each stage is the equivalent aside from when it comes to how cytokinesis is practiced.
<em>Plant cells separate the cytoplasm between the two new cores by framing a cell plate (new cell wall)between the cores.</em>
Animals cells achieve this by shaping a cleavage wrinkle which is a squeezing in at the center of the<em> </em><em>cell until two new cells have been framed with cytoplasm and organelles for each new nuclei.</em>
