Agriculture: Crop Production and Management

The primary purpose of terracing is to reduce erosion on steep slopes by creating flat plots of land. This contributes to sustainable crop production by preventing soil degradation and maintaining fertile land for cultivation.

Sprinkler irrigation distributes water across the entire field, potentially leading to overwatering and runoff, while drip irrigation delivers water directly to the roots, reducing evaporation and runoff. Drip irrigation is generally more water-efficient and can lead to higher crop yields.

Precision agriculture uses technologies such as GPS, GIS, remote sensing, and drones to collect and analyze data on crop yields, soil moisture, and crop health. This information is used to optimize crop production and management, reducing waste and improving yields.

<p>Remote sensing uses aerial or satellite imagery to monitor crop health, detecting issues such as pests, diseases, or nutrient deficiencies. This allows for targeted interventions, reducing waste and improving crop yields.</p> Signup and view all the answers

<p>The primary objective of crop rotation is to improve soil fertility, reduce pests and diseases, and increase crop yields. It achieves this goal by alternating between different crops, which breaks disease and pest cycles, adds nutrients, and reduces soil depletion.</p> Signup and view all the answers

<p>Simple rotation involves alternating between two crops, while complex rotation involves three or more crops. Simple rotation is easier to implement but may not provide the same level of soil fertility and pest control as complex rotation. Complex rotation, on the other hand, offers greater benefits but requires more planning and management.</p> Signup and view all the answers

<p>Biological control involves using natural predators or parasites to control pests. It contributes to a holistic approach by reducing the need for chemical pesticides, promoting ecological balance, and minimizing the development of pesticide-resistant pests.</p> Signup and view all the answers

<p>Soil fertility directly affects crop yield, as it provides essential nutrients and water for plant growth. Soil conservation techniques such as mulching and contour farming help maintain soil fertility by reducing erosion, adding organic matter, and promoting soil biota activity.</p> Signup and view all the answers

<p>Genetic modification involves breeding crops with desired traits to increase yield, disease resistance, and tolerance to environmental stresses. However, potential drawbacks include the risk of genetic contamination, reduced crop diversity, and unintended environmental consequences.</p> Signup and view all the answers
