Soil is very important for growing crops. If the soil is not in good condition, your plants will not grow well. There are three important things every farmer should know about soil: soil compaction, soil texture, and soil nutrients.
Soil compaction means the soil is tightly packed. The small spaces between soil particles are squeezed together. These spaces are important because they hold air and water. When the soil is too tight, water cannot move easily and plant roots cannot grow well. This can happen when heavy machines or animals move over wet soil.
When soil is compacted, crops grow slowly or become weak because their roots cannot go deep. A hard layer called a hardpan may form 10 to 20 centimeters below the surface. Roots cannot pass through this layer.
To avoid compaction, do not work on wet soil. Use light tools or machines. Plant cover crops like beans or grasses to help loosen the soil. Also, avoid walking or driving on the same soil over and over.
Soil texture means how much sand, silt, and clay is in the soil. These are small pieces that make up the soil. Sand is the biggest. It feels rough and lets water pass through fast but does not hold water. Silt is medium. It feels soft and smooth and holds more water than sand. Clay is the smallest. It feels sticky when wet and holds a lot of water but can become very hard.
A good soil for most crops is called loam. It has a mix of sand, silt, and clay — about 40 percent sand, 40 percent silt, and 20 percent clay. Loam holds water and air well and is easy for roots to grow in.
If your soil is sandy, water will run through it quickly, so you need to water often. If your soil has too much clay, it may stay wet for too long and plants may rot. You can mix compost or manure to improve any type of soil.
