Manure is a good choice for adding carbon and nutrients (P and K especially) to sandy and low carbon / compacted soils. However, adding manure to soils that are not suited to the mineral content of the manure can cause serious problems with soil fertility and future crop production. The main problems are excess potassium and phosphorous in the manure which build up in the soil locking up micronutrients like zinc, iron and manganese and reducing the uptake of magnesium and boron.

Manure does not add biology to your soils. Manure only supplies carbon which is a slowly available food source for the microbes. Compost adds the biology. Therefore before applying manure, always consider carefully the fertility and nutrient balance of your soils in combination with the analysis of the type of manure you have access to.
