Intensive crop farming is a modern industrialized form of crop farming.Intensive crop farming's methods include innovation in agricultural machinery, farming methods, genetic engineering technology, techniques for achieving economies of scale in production, the creation of new markets for consumption, patent protection of genetic information, and global trade.
A maize crop yielding 6–9 tonnes of grain per hectare (2.5 acres) requires 31–50 kilograms (68–110 lb) of phosphate fertilizer to be applied; soybean crops require about half, 20–25 kg per hectare. [21] Yara International is the world's largest producer of nitrogen-based fertilizers. [22]
This process is known as fertigation. By injecting a specified amount of concentrated fertilizer into the device, the injector mixes this into what is called a stock solution. To avoid overfertilization of plants that would result in the plant's death, the precise ratio of fertilizer to water must stay consistent.
The Food and Agricultural Organization of the United Nations (FAO) uses good agricultural practice as a collection of principles applying to on-farm production and post-production processes, resulting in safe and healthy food and non-food agricultural products, while taking into account economical, social and environmental sustainability.
In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss.
Foliar applications of seaweed fertilizer extract have been shown to improve the uptake of nitrogen, phosphorus, potassium, and sulfur in soybeans such as Glycine max. [59] Research has also demonstrated that brown algae seaweed extracts can improve tomato plant growth, overall crop yield, and resistance to environmental stressors. [60]
Phosphate rich organic manure is a type of fertilizer used as an alternative to diammonium phosphate and single super phosphate.. Phosphorus is required by all plants but is limited in soil, creating a problem in agriculture In many areas phosphorus must be added to soil for the extensive plant growth that is desired for crop production.
The practice of no-till farming is a combination of different ideas developed over time, many techniques and principles used in no-till farming are a continuation of traditional market gardening found in various regions like France. [10] A formalized opposition to plowing started in the 1940s with Edward H. Faulkner, author of Plowman's Folly. [11]
