You can add the salts of potassium sulphate(K2SO4) or ammonium sulphate((NH4)2SO4)
Both are soluble and will dissolve in the moisture in soil.
To neutralise a sample of soil, you must determine the pH of the soil sample either acidic or alkaline. Add lime (e.g. Limestone) to acidic soil to neutralise it. And add sulphur to alkaline soil which will neutralise it.
You can naturally add potassium to soil by using organic materials like banana peels, wood ash, or compost. These materials release potassium as they break down, enriching the soil with this essential nutrient.
Soil is naturally there, fertilizer is something that is put down to add extra nutrients
You can naturally add iron to soil by incorporating iron-rich organic materials like compost, manure, or leaf litter. Additionally, planting cover crops like clover or alfalfa can help increase iron levels in the soil.
You can naturally add zinc to soil by incorporating organic materials like compost, manure, or mulch that contain zinc. Additionally, planting zinc-accumulating plants like legumes or sunflowers can help increase zinc levels in the soil.
Sulphur (aka sulfur) is a naturally-occurring substance.
There are nitrogen fixing plants, such as legumes, that will add nitrogen to the soil naturally. When these plants die, they release nitrogen into the soil, making it available for other plants.
You add oxygen to sulfur to make sulfur dioxide.
they will naturally add fertilizer and from burrowing and tunneling will aerate the soil
If the soil pH tests between 5.0 and 6.5 on well-drained, sand to sandy loam. You must add sulphur to lower the pH to between 4.5 and 5.0. You should apply the sulphur the soil a year before planting and thoroughly mix it into the top 20 cm of the soil.
Sulphur can have both positive and negative effects on land. It is a component of soil fertility and essential for plant growth, but excessive sulphur deposition from sources like industrial emissions can lead to soil acidification, affecting nutrient availability and potentially harming plant life. Proper monitoring and management of sulphur levels are essential to maintain soil health.
You can naturally add potassium to plants by using organic materials like banana peels, wood ash, or compost. These materials can be added to the soil to provide a natural source of potassium for the plants to absorb and thrive.
