How does soil erosion affect the cost of crop production?
Soil erosion can increase the cost of crop production by reducing the fertility of the soil, which may require additional inputs like fertilizers to maintain productivity. It can also lead to loss of topsoil, which reduces water retention and nutrient holding capacity, ultimately affecting crop yield. Erosion control measures and soil conservation practices can help mitigate these effects and reduce the overall cost of crop production.
How is the fertility of soil renewed and conserved?
Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility.
Who studies soil and crop-crop- raising?
an agronomist
What is cover crop?
Any annual, biennial, or perennial plant grown as a monoculture (one crop type grown together) or polyculture (multiple crop types grown together), to improve any number of conditions associated with sustainable agriculture. Cover crops are fundamental, sustainable tools used to manage soil fertility, soil quality, water, weeds (unwanted plants that limit crop production potential), pests (unwanted animals, usually insects, that limit crop production potential), diseases, and diversity and wildlife, in agroecosystems.
How does fertilizer affect the earth?
Fertilizer can have both positive and negative effects on the Earth. When used in excess, it can lead to water pollution and eutrophication of water bodies. However, when used appropriately, it can improve soil fertility and crop yields, helping to meet the demand for food production.

Does soil formation affect the fertility of soil?
No, soil formation doesn't affect the fertility of soil but soil looses its fertility by being exhausted.
How does soil pH affect soil fertility?
soil fertility increases soil PH
What is the study of crop production called?
The study of crop production is called agronomy. Agronomy involves understanding plant genetics, soil management, crop rotation, and other factors that affect crop growth and yield.
How biotic and abiotic factors affect crop production?
Biotic factors such as pests, diseases, and competition from other organisms can negatively impact crop production by reducing yields. Abiotic factors such as soil quality, temperature, water availability, and sunlight influence plant growth and development, with suboptimal conditions leading to decreased crop productivity. Farmers must manage both biotic and abiotic factors to optimize crop production.
How do pesticides affect soil fertility?
Pesticides can have both negative and positive effects on soil fertility. While some pesticides can harm beneficial soil organisms and decrease soil organic matter, others can help control pests and preserve soil fertility by preventing crop damage. Using pesticides judiciously with proper application techniques can minimize negative impacts on soil fertility.
How is the fertility of soil renewed and conserved?
Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility.
What are the factors controlling crop production?
Factors that control crop production include climate (temperature, rainfall), soil quality (nutrient levels, pH), availability of water (irrigation), pest and disease control, access to sunlight, and management practices (fertilization, crop rotation). Additionally, factors such as technology, farming practices, and market demand also influence crop production.

Does soil expire and lose its fertility over time?
Yes, soil can lose its fertility over time due to factors such as erosion, depletion of nutrients, and compaction. This can lead to decreased crop yields and the need for soil amendments to restore fertility.
Which crop improve soil and soil fertility?
Pulses (legumes,beans,peas etc) enrich soil fertility. They have a symbiotic relationship with bacteria (rhizobia) and these are found in the root nodules of pulses. Members of the Rhizobium family fix nitrogen from the atmosphere to the soil and thus improve soil fertility.
