Sustainable agriculture is about using natural resources responsibly and preserving the environment for future generations. Sustainable agriculture can implement on any scale, from farming an individual garden to managing large plantations, including smart farming and urban farming. Sustainability is not a recent development in farming practice, agricultural science, or agricultural policy. Sustainable agriculture has adapted from three points of view: as an output system in achieving food self-sufficiency, as a management concept, and as a driver for rural community sustainability.
Sustainable agriculture has several techniques. They are crop rotation and selection, green manures and cover crops to control pests and weeds, planting at appropriate times of the year, minimizing tillage or other soil disturbance. In addition, sustainable agriculture uses different fertilizers to avoid creating excessive nutrients in the soil that can cause algal blooms, kill fish or other animals living in the water supply, and harvest rainwater rather than rely on freshwater sources.
Today, the increasing agricultural production demand aligns with the world's population, especially in urban areas. On the other hand, metropolitan areas have limited open space for farming and livestock. So it makes the agribusinesses and farmers need to produce crops productions more and more. It is absolutely a complex task. However, you can be a farmer, build your crop production in urban areas, and achieve food self-sufficiency.
There are some sustainable agriculture practices that you can implement in your urban landscape. These practices will help conserve water and energy, reduce pollution, achieve food self-sufficiency, and increase the health of your plants. Having a backyard garden is essential to practicing sustainable farming in your urban landscape. But, if you don't have it, you can utilize a balcony or terrace.
The first practice is to use mulch as a ground cover. Mulch is an organic material that helps maintain moisture levels in the soil and prevents weed growth. It also reduces the need for watering by up to 50%. The second practice is to plant drought-tolerant plants. These plants have been bred for their ability to survive in dryer conditions and will require less water than other plants. You can adapt horticulture techniques. You can read here for further information about it and horticulture plant references. The third practice is to install a rain barrel system on your property. This system captures rain runoff from rooftops or patios, preventing it from entering storm drains and being discharged into rivers or lakes where organisms can expose to contaminants like bacteria, pesticides, and metals. When practicing sustainable farming, you should make sure that you use water wisely and not waste any resources.
Sustainable agriculture is a way to increase crop yields in an environmentally friendly manner and must be able to optimize the surrounding conditions. For example, for precision agriculture in urban areas, you can use leftover food or leaves for organic fertilizer. With this, you have also applied the recycling process to the environment. You can quickly get homemade fertilizer to support sustainable agriculture practices in your urban landscape using:
Make your eggshells dry entirely. In a blender, pulse the dried shells until powder forms. Sprinkle the layer granules around your farm's crops. It works well because eggshells are almost entirely composed of calcium carbonate, the primary component of agricultural lime.
Please don't throw the aquarium water when you clean it up. Aquarium water contains nutrients and microorganisms from fish waste that seedlings can repurpose.
