Coordinate tasks for seed production and storage

In early times, hunter-gatherers (humans) lived off the abundance of the land, foraging for nuts, fruit, berries and edible plant parts. Without intervention of man, plants in nature propagated through seed which were spread by wind, water, animals, explosion and fire.
Seed is a fundamental requirement for plants to multiply.
After humans started cultivating the land, seed remained a basic and important agricultural input. For generations, farmers saved their own vegetable and grain seeds and maintained their own cultivars. This had advantages, because such seed (and the plants grown from them) were adapted to the environmental conditions of the specific region. Seeds can be bought from agricultural retailers. Buying low quality seed is cheaper in the short-term, but will generally be more costly in the long run because of lost profits from lower yields. Using quality seeds is a prerequisite for successful
crop production.

Coordinate tasks for compost production and use

Compost is the end product of a complex feeding pattern
involving hundreds of different organisms, including
bacteria, fungi, worms, and insects. What remains after
these organisms break down organic materials is the rich,
earthy substance your produce will love.
Composting replicates nature's natural system of breaking
down organic materials on the ground. In every forest,
grassland, jungle, and garden, plants die, fall to the ground,
and decay. They are slowly broken down by the small
organisms living in the soil. Eventually these plant parts
disappear into the brown crumbly material. This humus keeps soil light and fluffy.
As such, compost is an excellent soil amendment which improves the soil aggregate as well
as nutritious value of the soil.

Coordinate application of soil and crop fertility amendments and practices

Soil that is rich in nutrients is fertile. The basic goal of fertilization is to replace the nutrients that were taken out by plant growth. 

There are conventional and organic solutions to address a lack of soil fertility. These include recycle nutrients by applying animal wastes, apply fertilizers and/or increase microbial action.
