2. Describe the drip system of irrigation.

​

Answer 1

Answer:

Some differences between fertilizer and manure are:

1. Fertilizer is an inorganic chemical synthesized artificially while manure is a combination of inorganic and organic substances obtained naturally by decomposing cattle excreta, plant litter, and human wastes.

2. Fertilizer can add only a specific nutrient to the soil whereas manure can provide many useful nutrients.

3. A fertilizer cannot add humus to the soil whereas manure can.

Answer 2

1- manure is all natural animal droppings, while fertilizer may be natural but may also have chemicals and other unknown substances added to it. Examples of manure include rabbit, horse, cow, and chicken poop and bat guano. Examples of fertilizers include synthetic chemical blends, minerals, and compost from decaying organic matter.


2-Drip irrigation is a form of irrigation that saves water and fertiliser by allowing water to drip slowly to the roots of many different plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. It is done through narrow tubes that deliver water directly to the base of the plant. It is chosen instead of surface irrigation for various reasons, often including concern about minimising evaporation.
