For fertilizer.
Silts are naturally brought by rivers and streams when they overflow their banks. This process is a natural way for soil to be replenished and fertilized which benefits farmers' fields.
Farmers use quicklime as a soil amendment to raise the pH level of acidic soils, improving soil quality for certain crops to grow effectively. Quicklime also helps to break down organic matter in soil and can be used as a disinfectant to treat plant diseases.
Medieval farmers often practiced crop rotation by planting different crops in each field each year to help replenish soil nutrients. They also used animal manure as fertilizer and allowed fields to lie fallow periodically to restore nutrients naturally. Some farmers used techniques like terracing and contour plowing to prevent soil erosion and maintain soil fertility.
Intensive farmers ensure soil nutrients by using fertilizers tailored to specific crop needs, rotating crops to prevent nutrient depletion, and conducting soil tests to monitor nutrient levels. They may also use cover crops, manure, or compost to replenish nutrients and maintain soil health.
Farmers plow their fields to break up the soil, making it easier for planting seeds, improving soil aeration and water retention, and helping to control weeds. Plowing also helps to incorporate organic matter into the soil, which can improve soil fertility.
the manure next to the barn smells like crap.

Ground manure
A manure spreader does exactly what its name implies it does, it spreads manure. It is most useful in larger fields, where spreading manure by hand is not feasible.
They used levee canals to bring water to their fields.

Horse manure needs to be composted for about one year before it is safe to place around plants. You compost manure in mush the same way you would anything else. Once it reaches the consistency of dirt then it's safe to use. Most people seem to have their own 'recipes' for composts.
farmers use a mixture of manures and fertilizers so that the nutrients which cannot be fulfilled by the manures can be fulfilled by the plants and the nutrients which are not in the fertilizers can be fulfilled by the manures ex-NPK [nitrogen, phosphate and potassium] fulfill the nutrients which are not present in the manures
irrigation
Before tractors farmers used horses, mules, and oxen to till the fields.
We scoop it into a manure spreader and spread it across the fields before the hay comes in or between cuttings.
