Пояснения:

The technology discusses one of the sustainable land management practices that rehabilitate soil health by eradicating invasive species of Lantana Camara and using it to prepare biochar.

2.1 Краткое описание Технологии

Определение Технологии:

Lantana Camara, an invasive species in India, negatively impacts biodiversity and agriculture. Biochar made from its biomass can help manage the species effectively. Traditionally farmers produce biochar in soil pit kilns. Another low-cost portable kiln unit of biochar preparation is a viable option for rainfed areas, designed to work on the direct up-draft principle with bottom ignition and circular vents for uniform heat transfer.

2.2 Подробное описание Технологии

Описание:

Lantana Camara was introduced into India as an ornamental plant in 1809 by the British in Calcutta Botanical Garden. Lantana Camara negatively impacts biodiversity and native biota, disrupting the succession cycle, altering the structure and floral composition of native communities, and causing problems in agricultural lands in various regions of India. Its dense thickets outcompete native pastures, block the movement of grazers, and can cause poisoning. Its allelopathic activities also affect the growth of other species in its proximity. One of the measures to manage invasive species is by turning it into biochar.

Biochar is the charred biomass produced by slow pyrolysis in which organic material is heated under controlled temperatures (300-500°C) without oxygen. Lantana Camara is an ideal biomass for biochar production due to its high diversity and wide distribution. In addition to protecting ecosystems, invasive plant-derived biochar has potential applications in environmental remediation and soil amendment due to its unique structure, composition, and adsorption properties.

In the Mandla district of Madhya Pradesh, low-cost technologies for producing biochar are being practised. A low-cost portable kiln unit has been used in the Mandla District to cater to the needs of small and marginal farmers. One unit costs approximately Rs. 7000-12000 depending upon the design and location, including a metal drum, vent-making charges, and side fittings. The kiln is designed to work on the direct up-draft principle with bottom ignition. It is a vertical, single-barrel structure with a perforated base. The kiln has a square-shaped loading hole at the top, which can be closed at the end of conversion with a metal lid with a handle. The kiln has circular vents, a staggered arrangement to avoid rows, and a central vent to hold a wooden pole. Under open atmospheric conditions, the vents at the kiln base hasten hot gas movement through the bio-residues for uniform heat transfer by primary air movement. The kiln's top hole vents the released water vapours and hot gases. A strip of metal is welded around at 3/4th height of the kiln, to which two metal rods are welded on opposite sides to serve as lifting jacks. Dry Lantana Camara feedstock is placed inside the kiln unit, and a fire is lit at the bottom. Through a pyrolysis process, the organic compounds present in the biomass decompose at a specific temperature in an oxygen-limited environment.

Prior to use, the stalks/twigs of lantana are manually cut into appropriate pieces 15-19 cm long and 0.9-1.0 cm in diameter using a commonly used axe in order to achieve better packing density. Dry residues are a prerequisite to hasten satisfactory and quicker conversion. The dried residues of lantana are placed in the unit and are burned from the bottom in an oxygen-limited environment. Generally, the burning process takes 6-8 hours through a slow pyrolysis process. Once complete, the kiln is quenched with soil and left to cool for 3-4 hours. This simple and affordable biochar production method can help manage invasive plant species and benefit agriculture, the environment, and energy. The conversion ratio from biomass to biochar in the case of Lantana is around 20-25%. Farmers have reported of burning around 100 kg of dried Lantana biomass to get ~20 kg of biochar in one operation of the unit. The application rate of biochar varies from crop to crop and the type of soil and other characters. In studied project farmers do apply 20 kg of biochar mixed with 20 kg of cow dung and 20 kg of cow urine in an area of around 1 acre.

The burned biomass of Lantana after the process looks like the coal sticks, these sticks are pulverised through a pulveriser to make a powdered material for application in the field. The biochar is mixed with an equal quantity of cow dung and cow urine before the application. Some farmers also mix the native soils in biochar to get better results.

Пояснения:

Lantana camara is a highly invasive plant species that can quickly spread and take over private and common land. The plant can spread rapidly by seeds or vegetative propagation, and it can grow in various environments. This makes it difficult to control once it has established itself in an area. Lantana Camara outcompetes native plant species, reduces biodiversity and alters ecosystem processes. Additionally, the plant can be toxic to livestock and wildlife, and its dense growth can increase the wildfire risk.

5.4 Доступность и качество воды

Является ли солёность воды проблемой?

Нет

Происходят ли периодические затопления территории?

Нет

Комментарии и дополнительная информация по качеству и количеству воды:

The groundwater status is within the safe limits as per the reports by the Government of Madhya Pradesh. People use water from rivers, streams, and traditional small wells for domestic purposes. In the absence of good vegetative cover, the rainwater washes off the fertile topsoil from the farmlands making the land barren and resulting in the siltation of ponds and other water bodies. Further, a heavy infestation of invasive species such as Lantana Camara compounds the degradation.
The studied block Bichhiya is in a better position in terms of stage of groundwater development with 17%, while the average of the district is 7%. The stage of groundwater development refers to the % of groundwater being used for various purposes from the available groundwater in that area e.g. net annual groundwater availability in Bichhiya block is 9087 ham (hectare meters) while the existing annual ground water draft for all usage is 1523 ham, making it a 17% groundwater development stage.
