2.1.8 Phosphorus in Soil Phosphorus is also vital in photosynthesis and is involved in energy transfer. It increases resistance to disease. It also improves root development, encourages blooming, and rapid growth. It also improves microbial activity in the soil. An excess amount of phosphorus does not cause damage to plants.
If inorganic fertilizers are used, it will support quick growth of plants. More crops can be grown and more food could be produced by this way. Inorganic fertilizer can be stored for longer time and can used when required; it will support the idea of using inorganic fertilizers for quick production of crops. Another aspect of inorganic fertilizer is that its nutrients are easily available for plants, they are water soluble and plant roots can absorb them easily. Organic fertilizer need to be broken down into simple substances that plants can absorb them.
Most common garden plants will grow well in neutral to slightly acidic soil. (Organic Gardening) Radishes will be the experimental plant for this test. Radishes prefer soil well drained, loose, high in organic matter, free from stones, and a pH from 5.8 to 6.8(Cornell University). According to this, the radishes in this experiment are expected to have an increased growth in the soils that have a lower pH measure. In addition to affecting how nutrients are distributed throughout growing plants, pH levels also influence microorganism activity that adds to the decomposition of organic materials.
This allowed for a better crop to develop out of the ground each year because each of the different crops uses different nutrients out of the ground. Then once the grain was harvested it put different nutrients back into the soil. So if you keep on planting wheat in the same spot it will suck all the nutrients it needs to grow out of the ground. After a couple years of planting the wheat on the same land the farmers wouldn’t get as nice of a crop because the nutrients it needs to grow would be all gone. Using this method, the farmers were able grow better crops each year without putting a field to summer ... ... middle of paper ... ...t crop making them more stable and pushing the weak or not so stable farmers into the town in search of jobs.
