Adding the right amount of nitrogen fertilisers to crop soils is not an obvious task. Too much fertiliser will induce nitrate pollution and extra costs for farmers. Too little will decrease crop yields. Therefore agronomists have developped the nitrogen dilution curve, a simple math tool that helps farmers to calculate the best fertiliser amount to be applied. Reyes et al. show that the nitrogen dilution curve can be also used to manage grasslands.

Improving food production is now a difficult task because sustainable cropping depends upon many factors such as climate, pest management, land use and economics. Agronomists Craheix et al. provide guidelines to design software models that optimise the sustainability of farming systems.

Certifying organic crops is not an easy task due to the huge agricultural areas that have to be checked. Agronomists Denis et al. have designed a new, effective method that distinguishes organic and non-organic cotton fields with up to 86% performance in south-western Burkina Faso, West Africa. The method uses remote sensing from space.

Industrial coffee plantations are warming our climate because too much fertilisers are applied. Capa et al. tested coffee cropping using various amounts of fertilisers. They found that cutting by half the fertiliser amounts is still economically and environmentally sustainable.

Agriculture is actually facing major issues such as climate change, overpopulation, decreasing soil fertility, droughts and pests. There is therefore a need for new plants that tolerate novel stresses and contain higher minerals and vitamins. Wani et al. review the advantages and potential applications of plants modifed in their plastid genome, as an alternative to common genetically modified plants, that are plants modified in their nuclear genome. Biosafety issues and public concerns are discussed.

Agroecology is a novel concept that proposes the use of ecological tools and practices to replace actual harzardous farm management such as spraying toxic pesticides and degrading soil quality. However, this is actually little knowledge on which and how ecological processes should be used to improve farming. A review of agroecological and management sciences by Duru et al. provides tools to develop biodiversity-friendly agriculture.

The fall armyworm Spodoptera frugiperda is the larval life stage of a moth. This worm is a pest that can wreak havoc with crops if left to multiply. Biocontrol methods are currently developped to avoid the use of toxic pesticides. Agronomists Figueiredo et al. show that the yield of organic maize can be increased by 19% using the wasp Trichogramma pretiosum and a pheromone sex trap.

Organic wastes from agriculture and food industry are increasingly digested then recycled as cheap soil fertilisers. However, waste digestion and spreading is a potential source of greenhouse gases. The agronomist K. Möller reviews the consequences of waste anaerobic digestion on soil fertility and nitrogen compound emissions.

Grass species in pristine and agricultural landscapes are essential for biodiversity, soil quality and food production. For instance, grass flowers provide food for honeybees, grass roots decrease soil erosion and clean polluted waters, and grass diversity is known to influence the good taste of milk. It is therefore important to understand how grass species emerge, disappear and adapt to changing environmental conditions and agricultural practices. Da Silveira Pontes et al. review the latest advances on plant strategies in grasslands, using a recent scientific discipline named functional ecology.

Mineral fertilisers containing nitrates and ammonium are almost always applied in excess in crop fields. As a consequence soil waters and rivers are often contaminated by fertilisers, which induce pollution issues such as undrinkable water and unexpected algal blooms. Benckiser et al. review ecological techniques such as nitrogen fixation that recycle nitrogen within the soil, thus decreasing water pollution by nitrates.

Weeds increase bees and crop yields, yes they can!

Industrial agriculture is killing bees and other pollinators, thus paradoxically threatening future crop production because 35% of world crops need pollination. In the USA honeybees have declined by 59 % in 61 years, and weed diversity by 50 % in 70 years. Bretagnolle and Gaba report the unexpected benefits of weeds for bees and crop production.

Food security is an urgent matter, particularly in Sub-Saharan Africa. Many organisations are providing agricultural help to improve farming in poor nations. While such help is usually considered beneficial, unexpected negative consequences are possible. Scientists Schindler et al. analysed how agricultural assistance is planned by organisations. They found that methods used to plan agricultural assistance do not agree with the theory of sustainability.
