The Extension Program with a Territorial Approach, for the Integrated Control and Management of Black Mustard, carried out by the Agricultural Research Institute (INIA) thanks to funds from the Regional Government of Antofagasta, gives special importance to the training of local producers, in different areas of agricultural knowledge, always focused on weed control. On this occasion, the director of the program, Bárbara Vega, toured the El Loa province teaching how to make different biopreparations for fertilization and fumigation. All with materials that are available to farmers.

“The idea is that they can produce it themselves, since it is difficult to find some products in the area. And, in addition, the advantage of this is that it is practically zero or very low cost. So they themselves can access manufacturing and the other thing is that it adapts to what they have ”, explained the director.

On the other hand, the agronomist and director of the program, announced that they will experiment with flowers, to generate the attraction of natural enemies, which will control the insect pests that currently affect local crops.


During the workshops, where producers and extension professionals participated, they were able to see how, from inputs that they have on their farms, they can manufacture biol.

An organic foliar fertilizer, also called liquid biofertilizer, which is the result of a fermentation process in the absence of oxygen (anaerobic) of compost, yeast, milk or whey, a legume -which in this case was used alfalfa- water and ashes.

Also, they did Bokashi. An organic fertilizer of Japanese origin, which is obtained from the decomposition – in the presence of air (aerobic) – of plant and animal waste, which uses certain materials that allow it to accelerate the process. The finished bokashi provides nutrients necessary to stimulate the growth and development of crops.

And finally they learned how to make potassium soap from water, potassium hydroxide, and lard. This soap is an insecticide that is used to control certain pests that damage crops, such as whiteflies or aphids, among others.

In the Lasana valley, the farmer Ana Cruz Yapura, highlighted the workshop since they are knowledge that will allow them to develop their crops in a better way.

“It is nice to know how to prepare or keep our plants in good condition, our sowing. Besides, just as I have my animals, I have my own guano, so it would be nice to take advantage of that a little more. Sometimes you arrive and just throw it to the ground, without any prior preparation. And with this, of course, you get a little more out of that guano, “said the farmer.

The importance of these workshops is greater, since the program not only focuses on accompaniment to control weeds, but also seeks that, from an integrated management, implementing different techniques, enrich the Loino soils that is essential to recover its productive capacity.
