Agronomic educational garden: Educational Garden Agricultural Sciences

Agronomic educational garden

The horticultural teaching garden provides anyone interested with a partial insight into the diversity of agricultural crop species, forms and varieties. Primarily, it serves for self-study and, through occasional visits, enables the comparative observation and assessment of growth and development states, morphological characteristics and growth and development states.

Carbohydrate-rich grains Winter and summer types

Wheat and barley were already cultivated in Mesopotamia 10,000 years ago. From there they began a triumphal march across all temperate climate zones of the earth. Oats and rye are secondary crops. They were initially "weeds" in the cereals and were only cultivated and selected by chance. Today, cereals play a very important role in human nutrition worldwide. They are a raw material for baked goods and pasta, an important source for animal feed and - last but not least - they provide the raw material for beer production.

Protein-rich grains

Our native legumes are essentially grown for animal feed as protein feed. For the people of the world, they are an important source of vegetable protein and amino acids and are becoming increasingly important. Legumes have the special feature that their roots form a symbiosis with soil bacteria (rhizobia). These are able to fix nitrogen from the air and make it available to the legumes for the formation of protein or subsequent crops as a plant nutrient. Their ability to fix nitrogen means that mineral nitrogen fertilisers can be saved. For organic farming, legumes are therefore an indispensable component in crop rotation.

Oil rich grains - Winter and summer types

Rapeseed, sunflower, flax, camelina and safflower are available for the production of vegetable oils. Rapeseed plays a major role as a domestic oil plant. The press residues from oil production are used as animal feed. The oils are used in the food industry as well as in industrial processing for the production of e.g. paints or environmentally friendly fuels and lubricants. Oil plants are also an aesthetic enrichment for our cultural landscape due to the diversity of flowers.

Root- and tuber crops

The crop of root and tuber fruits is under the soil. This makes harvesting the crops very laborious. The potato, still a staple food, originated in South America and came to Europe in the 16th century. Through selection of the Silesian white beet, the sugar beet was developed in the middle of the 18th century and is of great importance as a supplier of sugar. Today, the fodder beet is less important as cattle feed. So-called energy beet is grown as biomass in biogas plants for energy production.

Forage crops

The forage crops include mainly grasses and a variety of legumes as well as some cruciferous plants. Forage crops allow the temporary establishment of a grassland-like population. They thus increase soil fertility and at the same time provide roughage for ruminants. By combining several species and varieties, growth factors such as light, water, nutrients and the footprint are optimally used. At the same time, the field food stocks offer an attractive picture and are often very valuable for insects due to their biodiversity.

Plants of grassland

Grassland is a type of land use that is grazed or cut and whose vegetation consists predominantly of perennial plants, mainly grasses. Grassland forms the feed basis for ruminants and other rough feedingstuffs. As a result, the use and management of grassland has traditionally been closely linked to animal feed quality requirements. In recent decades, dairy farming has increasingly used energy-rich fodder (concentrated feed, silage maize) from arable land, because even with intensive grassland management, the needs of high-performance animals can no longer be met solely by grassland forage.

New recycling alternatives with different quality requirements have developed as a result of the energetic utilization of grassland extensions in biogas plants and as a raw material for bio-based products. Grassland has other important ecosystem functions beyond the production of biomass, such as the conservation of biodiversity, water and soil protection and also the recreational function. Since these are usually more pronounced with extensive management, trade-offs to agricultural requirements can arise.

Grasses

With about 12,000 species, the sweet grasses are a large and varied plant family. 15 species are cultivated in Germany as fodder grasses and have economic significance, 12 of which can be seen here. Grasses are the most important species group in grassland and should account for about 60-80% in a balanced grassland population. Due to their pronounced vegetative propagation due to the formation of lateral shoots, they form a dense turf and are the basis for the yield and quality of the edible biomass. As the growth ages, the fiber content increases and the protein content decreases, so the fodder quality decreases.

Other grassland plants

In addition to the grasses, legumes and other herbs are always found in the grassland. They are the basis for biodiversity and shape the aspect of the stands.This diversity cannot shown in the Educational garden of Agriculture Sciences, visit the Hohenheim Gardens and the great outdoors.

Renewable raw materials and energy crops

Bioeconomy is the guiding theme of the University of Hohenheim. It is the vision of a sustainable economy in which renewable, biological instead of fossil raw materials are used to secure the supply of food, various products and energy for the population. The preservation of biodiversity is an important goal.

Short rotation crops

Willows and poplars are among the fast-growing tree species that may be grown on arable land. They have their strongest biomass growth in the first years after planting or harvesting and can therefore be harvested in "short rotation", i.e. repeatedly every 3-6 years. During harvesting, the entire tree is cut off about 15 cm above the ground and the trunks and branches are either laid down to dry or directly processed into chaff. The harvested biomass contains about 45% cellulose and 15% lignin. This makes it particularly suitable for paper production or for heat generation through combustion.

Perennial biomass grasses

After planting, perennial grasses can be harvested annually for up to 10 years, such as switchgrass, or 20 years, such as miscanthus. Both miscanthus and switchgrass belong to the heat-loving grasses and are characterised by a very high biomass yield. The biomass contains about 40% cellulose and 20% lignin. In China, where miscanthus occurs naturally, it is processed into paper or building materials. In Germany, miscanthus is currently used mainly as a fuel for heat generation. In the future, however, it will also be used in other ways, for example as a biogas substrate and animal bedding or for the production of ethanol, composite materials and lightweight concrete.

The flower-rich, Cup plant is native to North America and was already studied in Russia in the mid-20th century as a fodder plant for ruminants, but was found to be useless because it did not taste good to the animals. In the last two decades, however, it has been found that the taste does not matter to biogas plants and Cup plant is therefore well suited as a biogas substrate. Cup plant provides high annual biomass yields from the second year of establishment and provides plenty of food for pollinating insects during flowering. Cup plant has also been recognised as a greening measure since 2018. This means that farms that cultivate Cup plant are "rewarded" with about 60 € per hectare and year.

Perennial biomass plant mixtures

Biogas wild plant mixtures (WPM) contain annual, biennial and perennial flowering and predominantly wild plant species that are suitable for use as biogas substrates but have not yet been used as such. The WPM can significantly reduce tillage intensity over five to seven years. No pesticides are applied, with the possible exception of herbicides in the year of sowing. Even with lower annual biogas yields of WPM compared to maize, WPM can thus break up maize-emphasised crop rotations and enhance them from many social and ecological aspects (food for pollinator insects, habitat for small game, groundwater protection, landscape).
