What are the contribution of chemists to agriculture?
Chemists contribute to agriculture by developing pesticides, fertilizers, and herbicides to protect crops and increase yields. They also work on developing new crop varieties through genetic engineering techniques to create plants that are more resistant to pests and diseases. Additionally, chemists research ways to improve soil quality and optimize nutrient uptake for better crop growth.
How many pesticides are sprayed on crops a year?
There is no exact number, as it can vary depending on the type of crop and location. However, on average, crops are sprayed with multiple pesticides to protect against pests, diseases, and weeds throughout the growing season. Organic crops are not sprayed with synthetic pesticides, but may still use organic-approved pesticides.
Would growing two different crops and alternate rows reduce the farmers need to add chemicals to field?
Yes, growing two different crops in alternate rows can help reduce the need for chemicals in the field as it can disrupt pest and disease cycles, improve soil health, and promote biodiversity. This practice, known as intercropping, can also enhance yield stability and reduce dependency on synthetic inputs.
Does fertiliser burn?
A lot of fertilizer contains ammonium nitrate (NH4-NO3) which will detonate if it is pure enough and started with a blasting cap. If simply placed on a fire it may or may not burn depending on the purity of ammonium nitrate. If diesel fuel is added to ammonium nitrate fertilizer it is called a Fuel-Oxidizer fire, or fuel oxidizer bomb as the case may be.
Why must farmers continually add nitrogen when the element recycles naturally?
Farmers need to add nitrogen because crops remove it from the soil faster than it can be replenished through natural processes. While nitrogen does recycle naturally through processes like decomposition and plant uptake, the rate at which crops deplete the soil of nitrogen often exceeds the rate of natural recycling. This is why farmers supplement the soil with nitrogen through fertilizers to maintain optimal growing conditions for their crops.
What is the reason of four field system?
The reason for the 3 field system is so that 2 of the fields can grow crops and the 3rd of the fields wouldn't have anything growing but they would, put animals there to fertiliser the crops

What are the advantages and disadvantages of rivers?
Advantages:One advantage is that you have a constant supply of water and food.there is also a huge supply of all natural fertiliser which is good for growing crops.you can build dams for electricity and the body of water behind the dam can be a tourist attractionirrigation if there is a damDisadvantages:floods may destroy buildings+crops

Irrigation!
Why are volcanoes useful to people?
for farmers , because the soil is good for growing crops
What resource is found in Georgia's coastal plains?
Good growing soil for crops and such.
What is the importance of semiarid?
It has diffrent types of climates such as summer, good for growing crops, and rainy weather so you wont have to water the crops!
Why is nitrogen used in fertiliser?
Nitrogen is very important to many crops; without nitrogen the production is decreased.
