Which amendments increase soil fertility quickly?

Building Soil Fertility with Compost

Compost is a highly effective amendment for increasing soil fertility quickly. It’s made by decomposing organic materials like food scraps, leaves, and grass clippings, which releases nutrients like nitrogen, phosphorus, and potassium. A general rule of thumb is to add 1-2 inches of compost to the soil surface and mix it in to a depth of 8-10 inches. This can increase the soil’s water-holding capacity, structure, and overall fertility.

Using Manure to Enrich Soil

Manure from herbivores like cows, horses, and goats is a rich source of nutrients like nitrogen, phosphorus, and potassium. A general guideline is to add 2-4 inches of well-aged manure to the soil surface and mix it in to a depth of 8-10 inches. However, it’s essential to note that manure can also introduce pathogens and weed seeds, so it’s crucial to compost it properly before applying it to the soil.

Green Sand for Long-Term Fertility

Green sand, also known as glauconite, is a type of mineral-rich soil amendment that can provide long-term fertility benefits. It’s made up of iron-rich minerals that release slowly over time, providing a steady supply of nutrients like potassium, magnesium, and iron. A general recommendation is to add 1-2 pounds of green sand per 100 square feet of soil and mix it in to a depth of 8-10 inches. This can help to improve soil structure, increase fertility, and reduce the need for synthetic fertilizers.
