Soil improvement in agriculture means reworking the soil so that it holds water and nutrients again and the crop can reach them. That works through structure, humus, pH, trace elements and water-holding capacity. The soil analysis shows which measure fits.
Why arable soils decline
Every crop takes nutrients out of the soil. If more is removed over the years than returned, the soil becomes depleted. Longer dry spells and more frequent heavy rain add to this. Usually several causes act together:
Compaction
Heavy machinery, driving on wet soil and always the same working depth press the soil together. A plough pan or wheel tracks keep water on top and roots out of the subsoil. You see it in puddles after rain and in roots that bend off sideways.
Too little humus
Humus holds water and nutrients and makes the soil crumbly. If more is removed than returned, the content drops over the years. Light, sandy soils lose humus faster than heavy ones.
pH out of range
If the soil is too acidic or too alkaline, nutrients are present but less available to the plant. pH is part of every standard analysis and the first value to look at.
Missing trace elements
Plants need boron, copper, manganese, iron and zinc only in small amounts. If one is missing, it still limits yield. Many standard analyses do not include them, so it is worth requesting them from the lab.
Low water-holding capacity
A soil that stores little loses twice: in the dry period water is missing at the root, and in heavy rain it drains away and takes dissolved nutrients with it. Then you have to irrigate more often and supply more nutrients.
Soil improvement starts with the soil analysis
Without an analysis every measure is a guess. The lab report shows soil type, humus content, pH and the main nutrients. For targeted soil improvement the trace elements boron, copper, manganese, iron and zinc belong in it too. That way you only spend money on what the soil actually lacks.
Soil improvement measures compared
| Measure | Acts on | Works after | Lasts |
|---|---|---|---|
| Soil analysis | shows what is missing | at once | the basis for everything else |
| Liming | pH, structure | months | several years |
| Loosening | compaction | at once | until compacted again |
| Cover crops, manure, compost | humus, soil life | years | lasting |
| Soil conditioners | structure, nutrient retention, soil life | from the first season | several years |
| Water-storing granules | water-holding capacity | from the first rain | half-life of about 5 years |
The measures do not exclude each other. Liming and loosening create the conditions, building humus through the rotation is the long-term task. Soil conditioners with immediately available stable humus and a water store in the root zone work quickly and for several years. Six ways of storing water compared

Reworking soil with soil conditioners and water-storing granules
PowerGelee is a water-storing granule with high-quality active soil conditioners for conventional agriculture. The blend follows your soil analysis and adds what the soil lacks. The soil conditioners improve soil structure and keep nutrients in the root zone. Every blend contains stable humus that is available immediately. The water-storing granules make up for missing water-holding capacity.
The blend is worked into the root zone once, about 150 kg per hectare on average, and has a half-life of about 5 years. This rebuilds a depleted soil over several years. We do not give a yield guarantee. More on water-storing granules · View the products
What soil improvement brings the farm: time and money
A soil that holds water and nutrients needs less topping up. You notice that in two places.
- Time: You go out less often to top up water and nutrients. Every saved pass is hours on the tractor you have for other work.
- Money: Fewer passes mean less diesel, less machine wear and fewer labour hours. Nutrients that stay at the root are not leached and do not have to be supplied again.
On top of that come more evenly supplied stands that get through dry weeks better. Our customers report higher yields and larger fruit. See field comparisons · Testimonials
If you have a lab report of your soil sample, you can upload it to us. We tell you without obligation what your soil lacks and which blend suits it.
Frequently asked questions about soil improvement
What is soil improvement in agriculture?
All measures that improve the structure, water-holding capacity, nutrient retention and soil life of arable soil. They include liming, loosening, building humus through cover crops and organic fertilisers, and soil conditioners. It always starts with a soil analysis.
How long does it take to rebuild a depleted soil?
Several years. Compaction can be broken up in one season; building humus through cover crops and manure takes much longer. PowerGelee brings immediately available stable humus, further soil conditioners and a water store straight into the root zone. That works from the first season.
What is the difference between fertiliser and soil conditioner?
Fertiliser supplies the plant with nutrients. A soil conditioner has no substantial nutrient content. It improves the biological, chemical or physical properties of the soil so that water and nutrients are held and used better. That is how the German Fertiliser Act (section 2) defines it in essence.
How do I know my soil needs reworking?
By puddles after rain, a crusted surface, uneven stands and yields that decline despite fertilisation. Certainty comes from a soil analysis with humus content, pH, main nutrients and trace elements.
Who offers soil improvement for farms?
GeleeVital blends water-storing granules with high-quality active soil conditioners for each farm individually, based on the soil analysis. The product is called PowerGelee and is intended for conventional agriculture. Delivery is to Germany, France, Austria and Switzerland, and to other countries on request. The initial assessment of an existing lab report is non-binding.
