Loss of productivity

  • Sectors
    Objective

    Fogs have the potential to provide an alternative source of fresh water in dry regions and can be harvested through the use of simple and low-cost collection systems. Captured water can then be used for agricultural irrigation and domestic use. Research suggests that fog collectors work best in locations with frequent fog periods, such as coastal areas where water can be harvested as fog moves inland driven by the wind.

  • Objective

    What are biodigesters?

    A biodigester system utilizes organic waste, particularly animal and human excreta, to produce fertilizer and biogas. A biodigester consists of an airtight, high-density polyethylene container within which excreta diluted in water flow continuously and are fermented by microorganisms present in the waste. The fermentation process is anaerobic, i.e., it takes place without oxygen, and the bacteria responsible for decomposition are methanogenic (i.e., they produce methane, also known as biogas).

  • Objective

    Soil is a fundamental requirement for crop production as it provides plants with anchorage, water and nutrients. A certain supply of mineral and organic nutrient sources is present in soils, but these often have to be supplemented with external applications, or fertilisers, for better plant growth. Fertilisers enhance soil fertility and are applied to promote plant growth, improve crop yields and support agricultural intensification.

  • Sectors
    Objective

    Organic agriculture is a production system which avoids or largely excludes the use of synthetic fertilisers, pesticides and growth regulators. It can sequester carbon using crop rotations, crop residues, animal manure, legumes, green manure, and off-farm organic waste (Lampkin et al., 1999). It can also reduce carbon emissions by avoiding the use of fossil fuels used in the manufacture of the chemicals used to make synthetic materials.

  • Objective

    The introduction of new cultivated species and improved varieties of crop is a technology aimed at enhancing plant productivity, quality, health and nutritional value and/or building crop resilience to diseases, pest organisms and environmental stresses. Crop diversification refers to the addition of new crops or cropping systems to agricultural production on a particular farm taking into account the different returns from value-added crops with complementary marketing opportunities. Major driving forces for crop diversification include:

  • Objective

    Description

    Crop rotation consists in sequentially producing plant species in a given location by alternating crops every year, every two years or every three years. This diversified production system prevents the build-up of pests and diseases as well as the exhaustion of the soil that usually occur with production of a single crop (or crops of a single family) in successive agricultural cycles.

  • Objective

    Description

    Agroecology is a holistic production method that works at the agroecosystem level. It is based on adopting integrated management for resource conservation as well as diversifying and enhancing synergies among the components of the agroecosystem, balancing energy and nutrient flows and adapting productive activities to local conditions. It promotes a high degree of interaction among its components to preserve biodiversity and attain sustainable production.

  • Objective

    Researchers at Purdue University have developed an instrument/software that allows remote sensing of surface soil moisture from an airborne instrument using reflective electromagnetic radiation. This can provide the most efficient method to collect measurements and survey an entire field with high spatial density in a short period of time. It makes use of lower-frequency signals which are required to penetrate the soil. Resolution is determined only by the frequency of the signal, under the assumption of a near-specular reflection, not the antenna size.

  • Objective

    Soil water plays a critical role in the life of plants. They need adequate water to develop a strong root system and for cooling themselves.  Irrigation is about proper timing and maintaining the available water at the appropriate amounts.  When soil water drops below proper levels, crop stress develops that lead to loss of both crop quality and yield.  Over irrigation contributes to erosion, loss of nutrients and increase input costs. Growsmart provides a growing hardware suite of plug-n-play sensors that are the eyes and ears in your field.
