How do farmers care about soil health? According to experts, the cycle of rotation of different crops is important, but there is no universal solution for each region.
Farmers have long been at the forefront of developing healthy tillage and maintenance practices. The quality of waste on a farmer’s farm is essential for their livelihood – and their long-term sustainability. Experts recognize the benefits of a systems approach to soil health management.
Why Is Crop Diversity Important
Professor of Michigan State University and ecologist of soil and crop systems Dr. “We have a good understanding of how broad soil condition development is, and it starts with a diverse crop cycle,” says Siglinde Snape.
Crop Cover Is More Important Than Rotational Diversity For Soil Multifunctionality And Cereal Yields In European Cropping Systems
“Diversifying crops using rotary means such as alfalfa, grazing or small grains (wheat, barley and rye) is the first fundamental step towards better soil structure,” says Snape. “Corn residues prevent decomposition when left in the field, but corn roots do not support the formation of organic matter in the soil, nor in most cases improve soil structure. Soybeans help produce soil nitrogen, but also grow in the same season as corn.” To help with weeds and pest control, diverse crop rotations provide different food sources for soil microorganisms, which ultimately make the soil healthier.
Although it is important to prevent the erosion of maize residues in topsoil, the root system of other crops is necessary to support complex biological systems in healthy soil structures. Soil organic matter consists primarily of carbon and nitrogen from the plant’s root system, not debris or stones, so “farmers who grow with live roots,” says Snape, as well as cover crops and winter crops, have the secret to building healthy soil. Good structure Farmers who rotate corn and soybeans to increase soil fertility can also add cover crops to provide a variety of root systems that benefit the soil.
While crop systems with minimal and no-till soil (where the soil is not plowed or plowed) contribute to the overall health of the soil, the addition of different crop rotations can increase these benefits. “Our research shows that crop diversification can provide increasing benefits to current sustainable field practices such as manure or canning,” says Snape.
However, not all farmers can grow wheat. However, there are options, including rapeseed and mustard seed. “The challenge is to find a crop that works in current cropping practices and find a market for that crop,” says Snape. “Growers still have to pay the bills, so growing other crops must have the economic means and facilities for these new crops.”
Biodiversity And Agriculture
The bottom line of the field must also be kept in mind when developing a system to maintain good soil health. “Farmers have to pay the bills, but they want to make sure the land is healthy and productive,” Snape says. “We need to look at policies or programs that support crop diversification.”
“Not a single system works on every farm,” says Snape. “But the main thing is to work on developing a system that gets a diverse mix of living roots in the soil. It doesn’t look the same in all areas, but it’s important to come up with a working approach.”
This decade is crucial for the sustainable food and AG systems of the future. Are you the change agent we need? The current 7.2 billion population is expected to reach 9 billion by 2050. We already produce more food per capita Food production is based on technology Most arable land is already used and land is declining.
4 Nutrition: Malnutrition – Insufficient calorie intake 870 million are nourished, and food security in most developing countries promises a safe, adequate, nutritious and reliable food supply. 400 million obese malnourished in developed countries around the world – lack of adequate nutrients, vitamins, minerals and proteins can lead to disease

6 The Green Revolution: In the 1940s, technology won the Nobel Prize for increasing food production. Negative pollution for the ecosystem environment, loss of topsoil, loss of soil quality, increase of monoculture, loss of biodiversity
8 Biofuels: Biofuels – Biofuels Maize, algae, soybeans, palm oil Ethanol – The production of biofuels made from maize has doubled since 2007, causing large countries to grow and sell large quantities of maize as fuel instead of food.
Sustainable agriculture – Agriculture that does not degrade or degrades faster than soil, does not reduce pollution, does not preserve genetic diversity and preserves agriculture more sustainably, with less fossil fuels being an important goal.
Animal products: Foods made from crops make up the bulk of the human diet. Due to the growing consumption of meat by most people, the consumption of meat, eggs and milk is increasing and crops are being transformed into fidelity. 27.5 billion in 1961. Demand for meat is expected to double in 2011 by 2050
Crop Wild Relatives
A plant-based diet is more effective than a meat-based diet. 90% of energy is wasted from one tropical level to another. A plant-based diet can be used directly to feed people instead of feeding cattle. Poultry and eggs needed for animal husbandry require at least beef. Different animal products have different ecological traces.
13 Feeding plants: fattening farms – large areas where animals are kept CAFO – centralized animal feeding operations Large warehouses or pens increase production by keeping hundreds to thousands of animals at once, reducing costs More than 50% of the world’s pork and almost all poultry feed are made. 45% of the world’s grain goes to livestock Fattening Positive pastures for agriculture Reduced land requirements
Excessive amounts of urine and faeces, contamination of surface and groundwater and eutrophication are possible, pathogens from water can cause disease, so many animals can become infected and excessive use of antibiotics, hormones and heavy metals feeds animals to promote the growth of antibiotic-resistant microorganisms. Increases and increases the amount of meat that can be transferred to humans Fattening plants produce more greenhouse gases than odors and vehicles
16 Seafood aquaculture: Fish stocks around the world are declining Many stocks are on the verge of collapse
Why We Need Crop Diversity
18 positive effects Reliable food sources can be sustainable Reduces the pressure of the wild population Energy-efficient negative effects: Requires the use of antibiotics that can feed people directly used to feed fish Fish can spread disease or compete for resources.
Importance of Crop Diversity: Indigenous Species Prevent Failure Monoculture is Weak Many genetic diversity is missing 90% of diversity is lost in fruit and vegetable crops in the United States
20 Seed Banks: Seed Banks – Institutions that preserve and preserve a wide range of seeds 1400 Seed Banks worldwide stores 1 to 2 million different types of seeds Svalbard Global Seed Vault known as Doomsday Seed Vault, where millions of seeds are stored worldwide. Infection
21 Insects: Some insects are insects, some are important There are 800 crops that need insects for pollination – Fertilization of female plant germ cells with male plant germs or animals (birds, goats, insects) bees provide 3 billion. Pollination services rely on bees to pollinate only about 100 crops a year, which is about 1/3 of the American diet.
Integrating Traditional Crop Genetic Diversity For Mountain Food Security
The reason is not known, but there is a suspicion that pesticides reduce the use of pesticides, planting flowering plants can help restore bee populations 10.12.2016 – 7 species of bees have been placed on the list of endangered species.
23 “Insects” and weeds: insect pests Any plant competing with weeds and crops contains toxins that kill specific annoying species The worldwide use of pesticides, insecticides, herbs and fungicides has quadrupled since 1960. Pesticide resistance develops over time each year. increases with the development of the immune system, non-target organisms are killed and the insect population becomes difficult to control.
25 Biological control: Bio-control (bio-control) – Parasitic vessels using parasitic insecticides as a means of control are common control groups Insects can grow, especially if bio-control from a foreign ecosystem Preventing biological control is more difficult than using pesticides Bio-control should be carefully planned and regulated.
26 IPM: Integrated Pest Management (IPM) – Pest population monitoring biological control chemicals using mixed pest control techniques, use of transgenic crops in crop rotation only when needed, IPM can increase crop yields, reduce pesticides and save money.
