មតិកសិដ្ឋានបង្កើត: ផលិតកម្មចំណី Hog - 01 សីហា 2015

As densities of livestock increase, an industrious farmer finds ways and means to increase his farm’s nutrient stream for the benefit of his system. This article will describe methods and techniques necessary for a smallholder farmer to succeed with farm-derived hog feeds. As you read, remember that a farmer should first fully exploit the extensive (and more passive) existing systems on the farm, and only then consider intensifying their overall operation.

Tricho-Composting នៅបង់ក្លាដែស - 15 មិថុនា 2015

Tricho-compost is the material that results when spores of a beneficial fungus, Trichoderma sp. are used in the composting process. Trichoderma sp. are natural competitors against a wide range of harmful fungi; when it is added to compost, the latter can then work as an anti-fungal agent to protect crops in the field.

Increased awareness of the potential of neem tree by creating awareness of its potential would go a long way in promoting its acceptance for pest management and improvement of plant health, animal health, human health, and environmental health.

ធ្វើការជាមួយកសិករនៅក្នុងប្រទេសម៉ាឡេស៊ី - 15 កុម្ភៈ 2015

In Malaysia, agriculture is practised by a range of farmers – from subsistence cultivators of the soil to sophisticated, commercially-driven entrepreneurs. The latter group are quite adept at assessing the latest in technology and varieties, and already have established marketing channels. The challenge for an agronomist and scientist like me is determining how to effectively transfer scientifically-generated technology and know-how to the aforementioned subsistence cultivators.

In its simplest definition a forage is any plant material grazed or fed to livestock. However, a more specific definition that’s presented in this article focuses on plants (grasses and legumes) that are planted specifically to provide superior feed benefits to livestock due to: 1) higher protein content, 2) lower labour requirements, and 3) additional farming system or social benefits.

ប្រព័ន្ធ aquaponics ក្រវ៉ាត់បេតុងតម្លៃទាប - 15 តុលា 2014

Currently, we have two 16 x 1 meter floating raft troughs, and one 16 x 1 meter rock bed that are connected to six 1 cubic meter fish tanks by PVC piping (elements 1 and 2 above). We also have three smaller stand-alone aquaponics units that we use as example starter units. One of our major goals is to help others understand how aquaponics works. We accomplish this by presenting aquaponics in a way that is easy to understand and replicate. Our Concrete Ring System, a rock bed system developed by Scott Breaden at his home and at the ECHO Asia Impact Center, accomplishes this goal. It has helped us cut down on building costs, simplified the system, and allowed us to use locally available materials.

Today, if someone were to ask me to help build a small system on their urban rental property, would I use cement rings? The easy answer is yes, but....

រៀនពីកសិករ - 14 មិថុនា 2014

It was an afternoon of 2002 when I first read about SRI. As an extension officer in the District Agriculture Development Office (DADO), I started promoting SRI in the following years in the district of Morang, Nepal. Over this time I observed hundreds of attractive SRI fields and spent some years as a SRI activist. Looking at the results, I’ve learnt that different farmers face different problems, and that they adapt all techniques to suit their diverse circumstances and needs.

សញ្ញាសម្គាល់ដាំស្រូវរបស់ SRI - 14 មិថុនា 2014

This article is from ECHO Asia Note #21

Wanpen’s roller planting marker was developed from her experience. When a problem occurred, she would alter and develop the tool according to the problem and rice variety.

Wanpen’s tool was designed to be lightweight, easy to handle and convenient to use. The handle was designed so that the tool can be pulled. The tool makes parallel and perpendicular lines to mark the planting locations, optimizing space between rows so that the rice is easily organized in lines without using too much energy.

Observations of SRI in Nakorn Sawan, Thailand

This article is from ECHO Asia Note #21

SRI was first tried by farmers in Thailand over ten years ago. However, many farmers struggled to avoid trauma to the seedlings and to transplant young seedlings using human labor. Additionally, trying to draw lines (for even spacing of the transplants) was difficult and required labor and time.

In response to these challenges, several farmers began to practice the “parachute method” of rice transplanting, in which rice seedlings are “parachuted” into their place in the paddy using a throwing motion. Further advances on this have been created around Thailand, including a “dart transplanting method with roller planting marker line drawing” developed by Wanpen, the farmer in Nakorn Sawan whom I went to visit. With Wanpen’s innovations (methods ideal for SRI farming) a roller planting marker machine is used to make very straight lines throughout the field; these lines can then be used for spacing rice transplants, which are thrown like darts at the appropriate target. Both the dart method and rolling planter marker machine will be explained in further detail in the Thai Natural Farming Journal articles included in this ECHO Asia Note. Below, I will explain how Wanpen has utilized both innovations in her SRI practices.
