Some farmers in Ghana have adopted certain agricultural practices which are affecting their annual crop yields. In this article, I will highlight some of these practices which negatively affect their crop yields and reasons why they should stop.
First of all, the burning of crops remains. For instance, most farmers after maize or rice harvest burn the remains or husk of the crop primarily to clear the land for other agricultural purposes. Among other reasons like killing of pests and other resistant weeds are mentioned. However, this practice induces a plethora of problems including pollution and soil damage. The soil damage affects crop growth since there is loss of soil nutrients.
Secondly, flood irrigation. This is another notable example of bad agricultural practices. In this technique, water is delivered to the field by ditch, pipe or some other means and simply flows over the ground through the crop. Although flood irrigation is an effective method of irrigation, it is certainly not efficient compared with other options. In areas where water is scarce, if farmers keep using this technique, it will deplete underground water resources.
Thirdly, mono-cropping. Mono-cropping is the practice whereby a single crop species is cultivated on a particular land year after year. Mono-cropping upsets the natural balance of soils. Too many of the same plant species in one field area rob the soil of its nutrients resulting in decreasing varieties of bacteria and microorganisms that are needed to maintain fertility of the soil.
As a way of ensuring effective crop yield, the points explained above should be avoided by farmers in Ghana.
