The places across the world that are semi arid or experience average rainfall less than twenty inches in a year usually resort to dry farming. These are methods that were developed in the early nineteenth century in America. In these regions the farmers started to focus on growing crops that were drought resistant and could be grown in a non irrigated manner. These crops could grow on the little rainfall that they received.
Dry farming techniques
There are many techniques used in dry farming besides creating unique nursery supplies. For instance, the rain water is harvested in these regions by preventing runoff and evaporation as much as possible in these regions. The soil’s ability to hold back moisture is also maximized. It was found that crops like wheat grew well in such soil conditions as well as oats and corn. With the success of these techniques with dry farming and its scientific methods received worldwide acclaim. There is evidence that this form of farming was invented even earlier.
How the soil is prepared?
The main art is the sub soil treatment which was pioneered by people like HW Campbell. He created a machine that is known as the subsoil packer which created a firm organic soil in Perth in order to retain maximum moisture from rainfall. Other techniques include nursery supplies like seed beds that allow certain varieties of crops to be grown in the driest conditions.
In dry farming methods the farmers plant the seeds deep into the soil where the subsoil retains moisture. Contour farming is done so that rainfall can be directed onto the seedbeds and the runoff is prevented as well. The soil needs to be tended in a way that it is kept loose so that the ability to soak up moisture is greater. These are some dry farming methods that have been successfully implemented in many regions. It is one of the reasons due to which vineyards in California thrive and produce some of the best wines in the world.
Limitations of dry farming
Even though dry farming methods have been perfected in many parts of the world like US, often overuse of the methods has led to top soil being eroded extensively. Again, enough time is not given for the top soil to be replenished due to the increasing demand for food production on most farms. The dust bowl is a phenomenon that occurred as a result of too much erosion of the top soil. However the dry farming methods are the best methods to use in parts of the world that have semi arid terrains. Today, many urban growers are using such methods to do landscaping in an environmentally friendly way.
