Which factors improve soil fertility? select the three correct answers

Humus

Manure

Nitrogen

Explanation:

Soil fertility is a characteristic of soil that refers to the capability of soil to maintain and provide a suitable habitat for growth of agricultural crops, thus resulting to continuous productivity.

The fertility of soil may be influenced or enhanced by various factors which includes, the soil structure, organic matter, soil pH, and water retention among other factors.

Humus, nitrogen, and manure are among the factors that boosts or improves soil fertility, and thus enhances growth and sustainability of agricultural crops by the soil

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
