This is a very vague question. Here are some things to know before answering your question.
- What is your amount of water?
- What is the size of your land?
- How much annual rainfall is yours?
- But I will try to answer your question as best as possible.
In desert areas, the annual rainfall is usually about 1 inch or less and groundwater is not effective at all. But if you have good water, I recommend using a railgun instead of a drip irrigation system, and first of all before you try to grow something. Be sure to provide some cover for some organic material such as soil/sand. Straw, straw,
Use drip irrigation to plant mangrove trees, at first, they are very drought tolerant and grow well in the desert. You have to irrigate far less than any other plant or crop. You can stop irrigation after 2 months when they have new leaves. Cover the roots of each tree with straw or straw or wood chip to reduce water evaporation and begin the soil healing process. Also, use compost undercover. The first 2 months you have to irrigate like 1 liter in the morning and 1 liter in the evening. You can adjust the time depending on the nozzle of your drip. Once the trees start shading and the overall temperature drops down for your land, you can start growing your own things. But before that, remember that if you plant other crops, the heated sand particles will burn the leaves of your crop, and in the summer the sand itself becomes so hot that all the plants will burn.
Sprinkler / RailgunsThis system keeps the sand cool during the summer and prevents the plants from burning their leaves. You can install small sprinklers, but it may cost more or install railguns that overall costs are lower than sprinklers and are easier to manage. By using this system you can grow vegetable and any kind of crop from day 1 Keeping ground and compost is important in this process as well. This system is good for small root crops but not very good for trees but still, if you mix the soil well and cover it well then the plants can grow with it. This system will cost less to install and may earn you a start.
