Foods contain many nutrients that plants absorb from the soil, such as nitrogen, phosphorus, potassium and magnesium. Instead of buying ready-made fertilizer, you can create your own fertilizer from leftover materials. This is especially useful for home gardens and vegetable gardens. Associate Professor Andrey Starostin from Perm National Research Polytechnic University explains how to do this.

Industrial facilities use special equipment to extract nutrients from organic waste. However, you can get by with ordinary kitchen appliances at home. The waste must be crushed or squeezed and then dried.

Some homemade fertilizers can increase the uptake of mineral supplements by plants. For example, phosphate rock becomes more effective when used with an extract from vegetable leaves. Soaking the leaves in water can significantly enrich the flour with phosphorus.

Andrey Starostin also recommends using grains that are no longer fit for human consumption to create fertilizer. Fruit peels and stale bread also work well. These materials will help improve the soil structure and nourish the plants. Its convenience is that you can reuse food waste and turn it into useful fertilizer for houseplants and the garden.
