Land tenure is a very important aspect because of its implications for technology adoption. In this study, the producers surveyed responded both for the land they owned and for the land they rented. The values, in percentage, referring to own and rented area show that more than half are owners who, in turn, rent land to produce (58%). Other data that arise from it state that only 11% are limited to working land owned by them, while 31% rent.
From the point of view of the sustainability of agricultural systems, crop sequence planning is a key factor. The study showed a 15% double crop wheat / soybean, 71% first soybean and 14% maize. These figures indicate that in the region analysed, the appropriate sequences for the efficient use of natural resources (soil, water, light, etc.) and for the correct management of insectile pests and weeds, among others, are not carried out.
While a high proportion of the producers surveyed fertilize their crops (89 per cent), this practice was found not to be based on a diagnosis of nutrient availability relative to the need for the crop.
On the basis of the above, it emerges that the extension task of planning a crop sequence related to the efficiency of the system should remain an important point in the future work agenda.
As for the use of agrochemicals, it was established that 44% of respondents decide on pest control practices themselves, and of that percentage, 63% monitor their crops. This indicates a positive trend towards integrated pest management, basing its decisions mainly on the following criteria: toxicity to humans, residuality and selectivity of the product they use.
Those who do not monitor (37%) mainly take into account the recommendations of the supplier, the residuality of the product and the price of the product. These data support the need to continue with Integrated Pest Management (IPM) strategies as another priority line of outreach work.
With regard to the sources of information most commonly used by producers, the responses obtained highlight the importance of the private adviser, the cooperative adviser and the INTA. Fifty per cent mentioned the private adviser, 48 per cent referred to the cooperative adviser and 46 per cent referred to the INTA. It is noted that in 70% of the cases the producers indicated that their advisers were linked to INTA. This supports the long-standing institutional decision to consider advisers as key players in any technology diffusion strategy.
