why does the root of plant Bharti composites and the ground
Answers
Answer:
Explanation:
PROS:
Use of pesticides and fertilizers has agricultural benefits. Plants feed off soil nutrients required for their healthy growth and development. Over time, if these nutrient supplies are not replenished, soil will be incapable of sustaining plant life. Fertilizers are used to put these nutrients back into the ground. Organic fertilizers like livestock manure improve soil quality, but they release nutrients slowly. Manufactured fertilizers, on the other hand, give soil the quick boost needed during the growing season. Pesticides also provide an agricultural benefit by controlling pests that can damage or kill plants, saving at least 8 percent of crops annually.
CONS:
The pros of pesticide and fertilizer use are offset by the problems related to their toxicity. For example, pesticides used to protect crops from harmful pests often kill beneficial insects. Runoff of chemicals used in pesticides and fertilizers can drain into streams and lakes, and eventually our water supplies. Excess nitrogen from fertilizer runoff can cause excessive algae growth in rivers and lakes. Pesticides can also adversely affect the health of people who use them, as well as people who live near large agricultural areas, not to mention those who consume food treated with chemical pesticides. As many as 20,000 Americans suffer from pesticide poisoning each year, and the World Health Organization estimates 1 to 5 million people worldwide are affected by pesticide poisoning annually
The configuration of root systems serves to structurally support the plant, compete with other plants and for uptake of nutrients from the soil. Roots grow to specific conditions, which, if changed, can impede a plant's growth.
