Essay – Sol modifiant

L’un des avantages de l’utilisation de la méthode Mittleider est que vous n’avez pas besoin de modifier le sol. La pratique consistant à modifier le sol consiste à analyser les nutriments que les plantes ont enlevé sur le sol et à utiliser un additif pour réapprovisionner ce nutriment. Le sol peut devenir acide ou basique et doit avoir de la chaux (augmente le pH) ou du soufre (diminue le pH). Il existe un certain nombre de produits qui peuvent fournir une solution à court terme ou une solution plus durable à un élément manquant.

One of the advantages of using the Mittleider Method is that you do not need to amend soil. The practice of amending soil is to analyze the nutrients that plants have taken from the soil, and use an additive to restock that nutrient. The soil may have become acidic or basic, and need to have lime (raises pH) or sulfur (lowers pH). There are a number of products that can supply a short term fix or longer lasting solution to a missing element.

Name Description Application
Alfalfa Meal Primarily a plant source of nitrogen, Alfalfa Pellets (5-1-2) also contain trace minerals and triacontanol, a plant growth promoter. 25-50 lbs. per 1,000 sq. ft.
Azomite A natural source of minerals and trace elements, it is used in gardens as a re-mineralizer for soils and an anti-caking agent in animal feeds. 1-2 lbs. per 100 sq. ft.
Biochar Biochar is similar to charcoal, and can be used to increase pH of acidic soils. Long lasting, it serves to improve soil’s health through water retention, providing a healthy home for good bacteria and micro-organisms, and holding onto nitrogen. 50/50 mix of biochar and compost and apply about 1/4 lb per square foot.
Blood Meal A strong, slow release source of nitrogen, Blood Meal (13-1-0) is also chock-full of trace minerals. 10-30 lbs. per 1,000 sq. ft.
Bone Meal Granulated for easy application and quick uptake by plants, Bone Meal contains 20% phosphate and up to 23% calcium. 10-35 lbs. per 1,000 sq. ft.
Chicken Manure Composted Chicken Manure (3-2-2) provides a well balanced supply of nutrients and is excellent for mulching and moisture retention. 1 cu. ft. covers 200 sq. ft.
Coconut Coir Made from compressed coconut fiber, coir is an eco-friendly peat alternative! Works anywhere you would normally use peat moss, rockwool, vermiculite, perlite or pumice. It does not impart any nutrients, but does hold ten times its weight in water. 1 part coir to 2-3 parts soil.
Compost No amount of organic fertilizer can make up for poor soil. Compost provides a microbially active source of organic matter and other important soil builders required by plants. Up to 20 lbs. per 100 sq. ft.
Greensand Contains about 7% total potash, along with iron, magnesium, silica and as many as 30 other trace minerals. May also be used to loosen heavy, clay soils. 50-100 lbs. per 1,000 sq. ft.
Gypsum Used to loosen heavy clay soils, Agricultural Gypsum contains about 23% available calcium and 18% sulfur. 40-120 lbs. per 1,000 sq. ft.
Kelp Meal A great source of micronutrients and beneficial plant growth promoters. Kelp Meal also encourages tolerance to stresses such as pests, disease, frost and drought. 5-20 lbs. per 1,000 sq. ft.
Dolomite Lime Sweetens soil (raises pH in acidic soils) and is a quality source of calcium (Ca) and magnesium (Mg). Promotes healthy plant growth. 25-50 lbs. per 1,000 sq. ft.
Rock Dust Improves soil vitality and plant health. Rock Dust contains a broad range of trace minerals, many of which have been lost through the ages, by erosion, leaching and farming. 50-150 lbs. per 1,000 sq. ft.
Rock Phosphate Provides up to a 10 year reserve of phosphorous! Contains 27% total phosphate, 33% elemental calcium and many other trace minerals. Great for flowering plants. 50 lbs. per 1,000 sq. ft.
Shellfish Meal A source of calcium (23%), nitrogen, phosphorus and trace minerals. Contains chitin, which stimulates the growth of soil microbes that inhibit root-knot nematodes. 30 lbs. per 1,000 sq. ft.
Sulfur Lowers pH in alkaline soils. Elemental Sulfur contains 90% sulfur with 10% bentonite as a binder. Great around acid loving plants such as blueberry, azalea and rhododendron. 10 lbs. per 1,000 sq. ft.
Sul-Po-Mag Also known as sulfate of potash-magnesia, Sul-Po-Mag is a quick release source of potassium and contains 22% soluble potash, 22% sulfur and 11% magnesium. 5-10 lbs. per 1,000 sq. ft.
Worm Castings Gardeners know Worm Castings to be the most nutrient dense organic compost available. In soil, they retain water and release nutrients in a form that is easily used by plants. 5-10 lbs. per 100 sq. ft.
