Summary

This summary is machine-generated.

Living grass mulch significantly boosts soil health by increasing organic matter, nitrogen, phosphorus, and moisture. This sustainable practice also enhances microbial activity and improves fruit yield and quality.

Area Of Science

  • Agricultural Science
  • Soil Science
  • Ecology

Background

  • Bare soils are susceptible to degradation.
  • Living grass mulch is a sustainable practice to maintain soil health.
  • It also improves fruit yield and quality.

Purpose Of The Study

  • To quantitatively assess the effects of living grass mulch on soil properties, microbial communities, enzyme activities, and fruit productivity through a meta-analysis.
  • To investigate how managerial conditions influence these effects.

Main Methods

  • Conducted a meta-analysis of 93 peer-reviewed publications.
  • Quantitatively assessed impacts on soil physicochemical properties, microbial communities, enzyme activities, and fruit productivity.

Main Results

  • Living grass mulch increased soil organic matter (+24.11%), total nitrogen (+15.93%), available nitrogen (+16.22%), total phosphorus (+10.09%), available phosphorus (+12.92%), total potassium (+11.96%), and moisture content (+14.02%).
  • Increased bacteria and fungi abundance, and phosphatase and sucrase activities (9.9%–36.37%).
  • Improved fruit yield and quality, including plant yield, average fruit weight, and soluble sugar.

Conclusions

  • Understory grass cover enhances soil nutrients and microbial diversity.
  • Living grass mulch improves fruit yield and quality, supporting sustainable agriculture.
  • This practice is beneficial for the ecological development of smallholder plantations.

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:


Inorganic mineral matter, which constitutes about 40 to 45 percent of the soil volume.
Organic matter, also known as humus, which makes up about 5 percent of the soil volume.
Water and air, covering about 50...

The Roles of Bacteria and Fungi in Plant Nutrition 02:11

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

The collective bacteria residing in and around plant roots are termed the rhizosphere. These soil-dwelling bacterial species are incredibly diverse....

Key Elements for Plant Nutrition 02:35

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Fruit Development, Structure, and Function 01:58

Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Fruits can be classified based on the number of flowers and the structure of the carpels involved in their...

Responses to Drought and Flooding 02:41

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Under normal conditions, water taken up by the plant evaporates from leaves and other parts in a process called transpiration. In times of drought stress, water that evaporates by transpiration far exceeds the water absorbed from the soil, causing plants to wilt. The general plant response to drought stress is the synthesis of hormone...
