Agricultural Land Changes to Critical Land

Critical Land

Agricultural land can turn into a critical land. Knowledge of this critical land is beneficial to support the cultivation of plants in our garden. We will encounter greater obstacles when meeting this critical land than fertile land. How did the critical land occur? In essence, critical land occurs due to the continuous decline in land productivity. The decrease in soil productivity is caused by decreased soil fertility.

Critical land can occur by one or several factors. The occurrence of critical land is caused by factors:
Agricultural land that is continually cultivated without being followed by proper crop, soil and water management.
In some countries, critical land occurs due to shifting cultivation systems accompanied by logging and burning of land.
The practices of agricultural systems that do not take into account the concepts and efforts of soil conservation.
Critical land can occur due to natural disasters, such as field or forest fires, and floods.

The critical land is essentially land where the physical, chemical, and biological conditions of the soil are not productive in terms of agriculture. The critical land is mostly caused by physical damage to the soil. The physical damage to the soil is mainly due to the loss of topsoil which is fertile due to erosion. Such land leads to unproductive farming.

Another impact of erosion hazard is the destruction of the hydrological functions of agricultural land, the silting of rivers, reservoirs, dams, waterways, and environmental pollution.

The problems faced by critical land cover two main issues.
How to repair/rehabilitate degraded land becomes productive land.
How to prevent the rehabilitated lands from the physical damage of the land based on the geographical location of the land.

We need to consider in terms of cost and technicality to rehabilitate or prevent the emergence of critical land. Difficulties that are too great in dealing with critical land will burden our farming cultivation.
