Substantial reduction in food nutrients over the past 70 years caused by soil degradation- UN

*Tips for improving soil health


Every year on December 5, World Soil Day (WSD) is observed to raise awareness of the value of healthy soil and to promote the sustainable management of soil resources.


The campaign for World Soil Day 2022 (#WorldSoilDay) is "Soils: Where food begins." 


According to the United Nations," 95% of our food comes from soils.

18 naturally occurring chemical elements are essential to plants. Soils supply 15.

Agricultural production will have to increase by 60% to meet the global food demand in 2050. 

33% of soils are degraded. 

Up to 58% more food could be produced through sustainable soil management." 



Soils: where food begins


Did you know that a tablespoon of soil contains more living things than there are humans on the planet? Through the growth of plants, the world of soil, which is made up of living things, minerals, and organic materials, produces sustenance for both people and animals.


Similar to humans, good soil requires a balanced and diversified supply of nutrients in the right amounts. If soils are not managed sustainably, they will gradually lose fertility and produce nutrient-deficient plants. Agricultural systems lose nutrients with every harvest.


One significant process that degrades soil and endangers nutrition is soil nutrient loss. In terms of global food security and sustainability, it is seen as one of the most pressing issues.


The amount of vitamins and nutrients in food has substantially reduced over the past 70 years, and it is thought that 2 billion people globally are malnourished due to a lack of micronutrients, known as hidden hunger because it is hard to detect.


Some soils lose their ability to support crops due to nutrient depletion caused by soil degradation, whilst other soils have nutrient concentrations that are harmful to both plants and animals, pollute the environment, and contribute to climate change.


By addressing the growing challenges in soil management, raising soil awareness, and enticing societies to improve soil health, World Soil Day 2022 (#WorldSoilDay) and its campaign "Soils: Where food begins" aims to heighten awareness of the importance of conserving healthy ecosystems and human well-being.

Soil amendment 


The best method to improve soil texture is to add organic matter, such as compost or peat moss. Organic material is the remains of dead plants or animals. Your soil always contains some organic matter, but typically not enough for a plant's needs.


Your soil's tilth will be improved by decomposing organic materials. Organic material corrects clay soil by making it looser so that air, water, and roots may enter it, while it aids sandy soil by holding onto water that would otherwise wash away. It promotes advantageous microbial activity in all soils and offers certain nutritional advantages.


Compost 


Compost is a typical organic material used to improve garden soil. If you compost your garden waste, compost is free and a great amendment.


Manure


Local stables and farms are frequently good sources of manure. It should be composted and decomposed until it becomes dark, crumbly, and odorless. Fresh manure contains too much ammonia, which can burn your plants and irritate your neighbors.


Peat moss


To loosen the soil, peat moss is an inexpensive and effective option. And it is quite dusty. For easier handling, wet it first.


Grass clippings


Grass cuttings and other plant debris can be incorporated straight into the garden soil where they will gradually decay. Make sure the materials you use are seed-free and untreated with weed killers or pesticides.

Cover crops 


Cover crops, also called green manure, are cultivated on unused soil to till them in and allow them to decay in the garden. As they grow, the roots continue to loosen the soil, and the plants control weed growth.


Clover and vetch, are examples of cover crops from the legume family that enrich the soil with nitrogen. Most often, sites for vegetable gardens use cover crops.


Adding Nutrients


Organic fertilizers come from animal or plant sources. They gradually release their nutrients over time. In contrast to synthetic fertilizers, organic fertilizers provide a longer, sustained time of feeding rather than an immediate remedy.


There are different types of fertilizers based on the kinds of nutrients they contain, the ratio, and the amount. All three of the essential elements, nitrogen, phosphorus, and potassium, must be present in a fertilizer to be considered complete.


Although various plants have varying nutritional requirements, in most cases a balanced complete fertilizer should be used. To choose the right fertilizer for your plants, you must understand how to read a fertilizer label.


The type and quantity of fertilizer to use will also be suggested in your soil test report. You can also get extra nourishment for your soil from items like manure and fish emulsion for nitrogen, bone meal for phosphorus, and wood ashes for potassium.

To apply organic or inorganic (synthetic) fertilizer, follow the instructions on the label. Water-soluble fertilizers are applied with a sprayer or watering can, while some fertilizers are mixed into the soil in granular form.


The most significant method of amending the soil is by adding compost or another organic material. For instance, a yearly application of compost might replace the requirement for all other types of amendments. 


The ultimate purpose of creating good soil through amending is to change the pH, fertility, and texture of your soil to suit your plants. Organic matter will improve all types of soil when it is added.


The amount of further feeding, if any, will depend on how well your soil incorporates that organic matter. The pH of your soil will be determined by your plants.
