How agricultural production will be different in the future?
Future agriculture will use sophisticated technologies such as robots, temperature and moisture sensors, aerial images, and GPS technology. These advanced devices and precision agriculture and robotic systems will allow farms to be more profitable, efficient, safe, and environmentally friendly.
Why was the four crop rotation a positive change for farming?
Over the following two centuries, the regular planting of legumes such as peas and beans in the fields that were previously fallow slowly restored the fertility of some croplands. The four-field rotation system allowed farmers to restore soil fertility and restore some of the plant nutrients removed with the crops.
Which is the best indicator of healthy soil?
pH: pH is an important indicator of soil health because if there is inadequate soil pH, crop growth can be impacted and key nutrients may become less available.
What determines a healthy soil?
A healthy soil: Supplies nutrients, water and oxygen for healthy plant growth. Allows water to infiltrate freely. Resists erosion.
What are the indicators of soil quality?
Examples include topsoil depth, bulk density, porosity, aggregate stability, texture, crusting, and compaction. Physical indicators primarily reflect limitations to root growth, seedling emergence, infiltration, or movement of water within the soil profile.
How do you evaluate soil quality?
Soil quality cannot be measured directly, so we evaluate indicators. Indicators are measurable properties of soil or plants that provide clues about how well the soil can function. Indicators can be physical, chemical, and biological characteristics. Indicators can be assessed by qualitative or quantitative techniques.
Which is the lowest layer of the soil?

Is black soil well drained?
Disadvantages of Black Soil Formation Poor drainage system during flooding, and waterlogging. Black soil is low in fertility and poor in organic matter, nitrogen, phosphorus available and zinc. The use of fertilizers and the effects of manure on increased crop yield.
What is the difference between top soil and black earth?
Other “black earth” products do contain topsoil and may be labeled “black earth soil” or “black earth topsoil”. They’re slightly better, but again, you’d be better off with regular topsoil, which is usually amended with higher quality brown peat.
Is topsoil always black?
Topsoil refers to the upper portion of the soil structure, the nutrient-dense top that is frequently black colored because of the high amount of decomposing plant and animal material in it and the consequent high amount of nutrients.
Why does soil turn black?
Dark brown or black color in soil indicates that the soil has a high organic matter content. Wet soil will appear darker than dry soil. manganese oxide causes a black color, glauconite makes the soil green, and calcite can make soil in arid regions appear white. Organic matter tends to make the soil color darker.
Why is topsoil black?
Topsoils are dark primarily because they contain dead organic material in various stages of decomposition. The degradation of organic matter within the soil produces a substance called humus, which has a complex chemical structure and is composed of carbon-rich compounds that impart the dark color.
Is black topsoil good?
A high quality screened, organic, compost topsoil. This mixture has the most nutrients and is the richest topsoil.
Can you grow grass in Black Earth?
