2.1 Short description of the Technology

Definition of the Technology:

Organic mulching is a practice of applying thin layer of organic materials on the soil surface that decompose over time for the purpose of conserving soil moisture, reducing soil erosion, improving soil fertility, and reducing weed growth.

2.2 Detailed description of the Technology

Description:

It is a farm residue management technique of utilizing organic materials, such as locally available grasses and weeds, into useful purposes. These grasses and weeds are cut or chop into smaller sizes then applied and spread in layers over the ground or soil surface. It will then be served as cover to the soil.

Purpose of the Technology: The purposes of this technology are the following: to conserve soil moisture; to reduce soil erosion; to improve soil fertility; and to reduce weed growth.

Establishment / maintenance activities and inputs: In practicing this type of mulching, these are the following steps and activities: (1) Hauling of grass and weeds available in the farm; (2) Shredding of grass and weeds using the shredder; (3) Spraying of Indigenous microorganism (IMO) solution to the shredded grass and weeds; and (4) Spreading of the shredded materials (about 1 inch thick) in the vegetable beds after transplanting the crops.

Natural / human environment: Master’s Garden of Mr. Ambrocio Acosta is located at Barangay Puguis, La Trinidad, Benguet. The province is Type I climate under the Coronas system of classification with distinct wet and dry seasons with an average annual rainfall of 3,879 mm. The dry season is from November to April while the wet season is from May to October. The farm has an elevation of 1,342 meters above sea level with less than 40% slope. The farm was manually terraced with UV treated plastic shed. The production system is manually managed and cultivated by Mr. Acosta and his two farm laborers.

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
Organic mulch conserves soil moisture therefore reduces the need for frequent irrigation.
Prevent soil erosion by protecting the soil surface.
Organic mulch contributes nutrients and organic matter to the soil when decomposed.
Organic mulch encourages earthworm activity and other beneficial soil microorganisms.

Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Organic mulching lessens the frequency of irrigation, weed control and fertilizer application; It hereby eliminates the use of chemical herbicide and fertilizer. Moreover, it prevents surface runoff by providing soil cover and also reduces soil water evaporation by modifying or keeping the soil temperature constant. How can they be sustained / enhanced? Increase awareness towards organic farming.
Increase the ability of the land users to become resourceful. How can they be sustained / enhanced? Possible incorporation of other organic materials.
Turning farm residue or waste into useful material. How can they be sustained / enhanced? Impose proper waste segregation to ease the collection and hauling residue/waste to be used.
Simplicity of the procedure. How can they be sustained / enhanced? Keep the procedure simple or if there are some modification, it should be practical and can be easily adopted by the land users.

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view	How can they be overcome?
High cost of investment for the shredding machine.	Look for an alternative method of shredding or reducing the size of raw materials to be used such as manual chopping when farm operation is small scale.Otherwise, invest on shredder when farm operation is at large.
