What are the causes of decline in crop yields?
Weeds, Pests, and Diseases.
Why do farmers use chemicals on their crops?
Farmers use chemicals on their crops to control pests, diseases, and weeds. This helps to increase crop yields and protect the quality of the produce. However, the use of chemicals needs to be carefully managed to minimize environmental and health impacts.
What positive affects do weeds have on crop yields?
If you have too many weeds, they kill the corn. but dont worry about alalfa or hay. they have strong enough roots to handle lots of weeds.
Why do agricultural use pesticides?
Agricultural pesticides are used to control pests such as insects, weeds, and diseases that can damage crops and reduce yields. Pesticides help farmers protect their crops and ensure a higher quality and quantity of produce. Proper use of pesticides can help increase agricultural productivity and ensure food security.
Why do farmers increase crop yields?
Higher yields = increased income.
Why do people use herbicides?
People use herbicides to control or eliminate unwanted vegetation, such as weeds, in agricultural fields, gardens, and lawns. Herbicides help increase crop yields by reducing competition for nutrients, water, and sunlight.
Why do farmers destroy weeds?
Farmers destroy weeds because they compete with crops for essential resources such as water, nutrients, and sunlight, which can significantly reduce crop yields. Weeds can also harbor pests and diseases that may harm crops, leading to further losses. Additionally, by controlling weed populations, farmers can improve the overall quality and marketability of their produce. Effective weed management is crucial for maintaining healthy and productive agricultural systems.
What do people plough?
People plough fields to prepare the soil for planting crops. Ploughing helps break up the soil, control weeds, and create furrows for planting seeds. It is a common agricultural practice used to improve soil structure and increase crop yields.
Do genetically modified crops increase food yields and cost less?
There is no evidence that suggests GMO foods have increased yields or cost less.
Why do farmers spray pesticides and insectidies in the fields?
Farmers spray pesticides and insecticides in the fields to protect crops from pests, diseases, and weeds that can reduce yields and quality. These chemicals help to control and manage harmful organisms that can threaten the health and productivity of the crops, ultimately ensuring a successful harvest.
Similarities between traditional and modern biotechnology?
both are technology to increase yields
How did the crop rotation system that developed in Britain during the agricultural revolution increase crop yields?
Crop rotation system developed in Britain during agricultural revolution increase crop yields by increasing nutrients in the soil.
