Honestly‚ this was a very interesting project for me because I had never done an experiment like such. Having carried out the measurement of the site parameters in the field I feel that it can be done by ordinary farmers. The farmers have much more knowledge about how their farms and soil work. I had no special training nevertheless knowledge of how farms developed good crops; if I can do

is a tool used in farming for initial cultivation of soil in preparation for sowing seed or planting. It has been a basic instrument for most of recorded history‚ and represents one of the major advances in agriculture. The primary purpose of ploughing is to turn over the upper layer of the soil‚ bringing fresh nutrients to the surface‚ while burying weeds and the remains of previous crops‚ allowing them to break down. It also aerates the soil‚ and allows it to hold moisture better. In modern use

can reach a new pH level by interacting with soil. If water has a pH that is too high or too low‚ it can be life threatening to aquatic species and can corrode metal structures. After finding this out‚ I decided to test if water could reach an extreme pH just by interacting with soil around it. The question for this experiment therefore became the following. Will interaction with soil change the pH of water? I hypothesized that if water interacts with soil for three days‚ then the pH of the water will

Soil Erosion And Conservation SOIL EROSION AND CONSERVATION Erosion Erosion is the removal of soil particles by the motion of wind or water. Soil erosion is one of the major concerns of modern agriculture throughout the world. The fallowing contributes to soil erosion: Misuse of land‚ Mismanagement of arable land‚ Indiscriminate felling of trees‚ Overgrazing‚ Poor soil and water management Erosion causes or Results in a: Decline in soil fertility‚ Water supply‚

Activity 1 – Water Holding Capacity & Capillary Action of Soil 1. Grain size and the amount of air space between particles. 2. Water-holding capacity determines the amount of water a soil is capable of holding. Since water is a necessity of any agricultural endeavor it is important for a soil to have a good water holding capacity. 3. We’d add humus because it has the highest water-holding capacity. 4. It would benefit plants in a dry climate because it could easily take groundwater

The best speed to seperate the components of this soil sample would be 5000 rpm because there are only two layers so the soil is more separate in that speed. Describe in which layers you are likely to find the organic matter‚ gravel‚ sand‚ silt‚ and clay at the following speeds:
