Boron 24 25 VC 30% better
Particularly in alkaline soils use of leaf compost can lead to micronutrient defiencies. The use of vermicompost is a better option for an ideal pH and better nutritent content and availability.
Use 1 par vermicompost to 4 parts leaf compost for full season use and the pure vermicompost for organic starter nutrients.
Vermicompost is really not a compost but earthworm castings are a manure will very useful properties including superior availability humic acids combined with soluble nutrients.
Well-decomposed compost helps lower the pH of garden soil over time. Amending your soil each season with compost, which is rich in organic matter, is by far the best way to make your soil more acidic because it is done gradually and creates the most benefits for plant growth. Manure is typically between pH 8-12, but don't expect manure to affect pH levels in soil.The significant effect on the organic carbon, total nitrogen, and available phosphorus of soil was depicted after the application of compost. The addition of compost, aid in raising the pH of soil that agrees the neutral range of 7.0–7.2 in both soils.35 and 100 percent of total P in compost is released depending on the time elapsed after application (35% available after 1 year, 100% available after 3-5 years). Composts originating from manures have the highest amounts of P. compost both improves soil's ability to hold nutrients and delivers much-needed nutrients. It improves nutrient retention by increasing the soil's cation exchange capacity (CEC) and then it delivers needed food for the plants in the form of nitrogen, phosphorus, and potassium
The pH of finished compost depends upon the raw materials used for its preparation. It can either be acidic or alkaline. Compost incorporation in soil buffers the pH. It absorbs ions and tends to keep the pH of soil from changing too much. In some acidic/alkaline soils compost can absorb enough ions to move the pH closer to neutral. These will be small changes. Do not expect huge pH drop by adding some compost. Nutrients availability for crop growth is highly improved due to the presence of nutrients in compost
Bonsoir!
- Le bio compost peut agir sur le pH , ce dernier permet de connaitre le niveau d'acidité (favorable à la nutrition).
- Le compost est censé être doté d'éléments fertilisants absorbables par le système racinaire des plantes.
- Il existe incontestablement des différences de composition biochimiques (nutriments à doses différentes) de compost, lesquels sont recommandés pour l'amélioration des rendements.
Bonsoir/ good evening Dr. Sunita Gaind
Thank you for your answer.
