Describe two ways that chemicals can be used to improve crop yields?
1. Chemicals can be used to eliminate pests that harm the plants, such as a pesticide. 2. Chemicals can be used to add the nutrients that the crops need from the ground, such as adding Nitrogen for corn growth.
Chemical that provides nutrients to help crops grow?
Fertilizer. Fertilizers are substances that supply essential nutrients to plants, such as nitrogen, phosphorus, and potassium, which are vital for their growth and development. They are commonly used in agriculture to enhance soil fertility and increase crop yields.
What can too much fertiliser cause?
Fertilisers increase crop yields but cause the problem of eutrophication when they're ... However, if too much fertiliser is used it can pollute water supplies.
How does the crop rotation system increase crop yields?
If we grow a crop continuously in the same field for many years, it results in to various problems such as 1) deficiency of same types of nutrients and 2) build up of diseases and insect-pest. So crop rotation is used as a system of growing a sequence of different crops on the same ground so as to maintain or increase its fertility.
Chemicals used to increase crop growth?
Fertilizers containing nitrogen, phosphorus, and potassium are commonly used to increase crop growth. Other chemicals like micronutrients (e.g. iron, zinc) and growth regulators may also be used to promote healthy plant growth and increase yields. It is important to follow proper dosage guidelines to avoid negative impacts on the environment and human health.
Why do you need artificial fertilizers?
Artificial fertilizers are needed to supply essential nutrients to plants that may be deficient in the soil. They help improve soil fertility, promote plant growth, and increase crop yields. Artificial fertilizers can also be used to correct specific nutrient imbalances in the soil.
Econamic importance of fungi?
Fungi can increase or decrease crop yields as mutualists and pathogens of plants, they are responsible for making dough rise and alcohol, they cause and prevent the spoilage of a lot of food, they are responsible for the production of some cheeses, they produce many of the antibiotics necessary to treat illnesses, and they are used by industry to produce chemicals that are hard to synthesize in a lab.
What are the uses of chemical Fertilisers?
Chemical fertilizers are used to provide essential nutrients to plants to enhance growth and increase crop yields. They help replenish soil nutrients that may be depleted due to intensive farming practices. Additionally, chemical fertilizers can be tailored to specific plant needs, making them a versatile tool for agriculture.
What economic importance of FUNGI in a phrase?
Fungi can increase or decrease crop yields as mutualists and pathogens of plants, they are responsible for making dough rise and alcohol, they cause and prevent the spoilage of a lot of food, they are responsible for the production of some cheeses, they produce many of the antibiotics necessary to treat illnesses, and they are used by industry to produce chemicals that are hard to synthesize in a lab.
Why does clear polythene increase the yield of lettuces?
Clear polythene sheets can be used as covers for lettuce in order to extend the growing season into colder months and increase yields. Heavy polythene can also be used as a greenhouse cover in order to grow lettuce in cold months and increase yields.
A practice which can be used to increase crop field?
fertigation, pest managment
What is a fertilliser?
A fertilizer is a substance added to soil to enhance plant growth and improve crop yields by providing essential nutrients like nitrogen, phosphorus, and potassium. It enriches the soil and helps plants to develop strong roots, lush foliage, and abundant produce.
