Food systems face significant challenges that include increasing demand for agricultural products and accelerating environmental degradation. Regenerative agriculture has emerged as concept to reduce environmental harm while maintaining or even improving productivity. However, adoption of regenerative agriculture remains limited. This partly due to the absence of a shared definition and a standardised process to monitor, assess and report regenerative agriculture outcomes. To address this gap, SAI Platform, a member-led organisation within the food and beverage sector, collaborated with stakeholders to develop a global framework for regenerative agriculture. Drawing from a review of existing frameworks and consultations with SAI Platform members, farmers, and academics, we developed a framework that defines regenerative agriculture as an outcome-based approach that enhances environmental impact. It includes eight regenerative agriculture outcomes across the environmental areas of soil health, biodiversity, water and climate and suggests indicators to quantify progress. The framework process emphasises the need to understand local contexts and farmer needs when implementing regenerative agriculture. It does so through a four-step process that includes (i) a context analysis to identify key material criteria of a production system, (ii) the prioritisation of outcomes based on the context analysis, (iii) the selection of practices to achieve improved performance against prioritised outcomes, and (iv) the development and implementation of continuous improvement plans to monitor and report progress. Farm groups or individual farms can use this framework to independently verify the implementation of the steps defined in the framework and claim different performance levels for progress towards regenerative agriculture. These claims create a foundation for regenerative agriculture programmes, incentive mechanisms, and corporate reporting. While the framework is a starting point, collaboration and refinement are necessary to address evolving challenges in implementation. SAI Platform commits to research and stakeholder engagement to continuously improve the framework and support fair transitions towards regenerative agriculture.

Growth and digestive enzymes were studied in alevins of Arctic charr raised on six commercial diets that differed in protein source and level. There were links between diet composition (protein quality), fish performance and proteolytic and amylase enzyme activities. Trypsin and amylase activities were up to 10‐fold higher in charr fed high protein (65–70%) diets than in fish fed live feed. A depression of pancreaticenzyme activities was noticeable when charr were fed starter diets in which fish meal was partially replaced by soybean meal. Specific growth rates (SGR) showed a cyclic pattern during early ontogeny of charr and SGR was highly correlated with food conversion efficiency. Activities of pancreatic enzymes also demonstrated a cyclic pattern but the periodicities of the growth cycle (50.6 days) and those of the enzymes differed. We hypothesize that both photostimulation and feedback responses might be involved in pancreatic responses in fish, which result in cyclic growth patterns.

In Finland, manganese deficiency in sugar beet has traditionally been controlled by spraying the foliage with manganese sulphate. According to field experiments, placement of an acid compound fertilizer seems to provide a new possibility of controlling manganese deficiency of sugar beet in heavily limed fields. In 1-year experiments carried out in 1984—1985 in seven fields which showed slight symptoms of manganese deficiency, conversion from top dressing to the placement technique alone increased the availability of soil manganese to sugar beet. The availability was, however, best safeguarded only when manganese (0.7 %) was added to acid compound fertilizer and applied by the placement technique. Placement of manganese (25—30 kg/ha MnSO4; Mn 26 %) together with acid compound fertilizer increased the root yield by 2.0 tons (+ 7%) per hectare in average compared to placement of manganese-free compound fertilizer. The new method of application did not have a significant effect on the quality of sugar beet.

In pot and field experiments carried out in 1979-1981, the systemic funqicide hymexazol prevented satisfactorily soil borne damping-off of sugar beet caused mainly by the fungus Pythium debaryanum auct. non Hesse. The results with the combination hymexazol + thiram were still better. This treatment gave very good protection against the disease up to about two to three weeks after emergence, increased the yield on the average by 5-10 % and produced considerably thicker and denser stands. Thereafter a large number of beets may have become infected, but no great damage was caused as only few died. Band spraying at emergence using hymexazol with a large amount of water as well as spraying into the seed furrow prevented the outbreak of the disease almost completely. Liming had little effect on damping-off.
