While blood, fish and bone is one alternative to synthetic fertilisers, vegetarians can rest assured that there are plenty of other adequate fertiliser options out there. Sources

Both bone meal and blood meal act as potent nutrient amendments, and together, they work even better. Is Blood Meal a Good Fertilizer Choice? There are three general types of fertilisers: mineral fertilisers produced from mined minerals such as phosphorous and potash; organic fertilisers made from organic materials such as bone or leaves, and industrial fertilisers, which are made by chemical Yates Dynamic Lifter can be used for all plants, lawns, and gardens. It is a natural slow-release fertiliser with a neutral pH that improves soil organic matter content, increases the water-holding capacity of the soil and enhances the cation-exchange capacity of the soil. Blood Fish & Bone is an organic-based general purpose plant food which provides the major nutrients required for strong healthy growth. This granular fertiliser contains three active ingredients - nitrogen, phosphate and potassium. The nitrogen encourages strong growth and green, rich foliage whilst the slow release phosphate increases root growth. Most vegetarian and vegan fertilisers have an NPK ratio that is much lower than Growmore. Organic fertilisers release their nutrients more slowly as they are broken down by bacteria in the soil. However, chemical fertilisers like Growmore are faster acting than organic fertilisers, making them a better choice if plants are low in nutrients and need treating urgently.As bone meal is water-insoluble, it needs to be broken down before the plant can absorb it, either by soil acidity or by microbial activity producing acids. According to the Colorado State University, it can only be broken down in acidic soil (pH < 7.0) and releases its nutrients over a span of 1 to 4 months. [6] History [ edit ] People who want to grow plants without using chemicals often choose blood, fish and bone fertiliser. This is an organic fertiliser literally made from blood and bones ground up into a powder. While blood, fish and bone is considered a good fertiliser as a natural source of all three major nutrients, its main components are by-products of the slaughter industry and leftovers from fish processing plants. Its use, therefore, might cause concern for vegetarians and vegans looking to avoid animal-based products. There is no one fertilizer that will support all plants, but the standard all-purpose blend of 5:5:5 or 10:10:10 works well for most plants.

A: There’s no hard and fast rule here, as every plant has different nutritional needs, and every soil profile does too. For consistent applications during the growing season, give your soil a little bit every 2 to 3 months. It’s a combination of dried animal blood (blood meal) and ground-down hooves and bones (bone meal) that are left over when the animal carcasses are processed.Monro JA, Leon R, Puri BK (2013).

While fertilisers are extremely helpful for growing plants, the mass use of synthetic fertilisers containing high amounts of nitrogen and phosphorus has had a damaging effect on the environment. Problems known to be caused by synthetic fertilisers include causing higher than normal growth of algae, making it a toxic hazard to fish and marine life, and contributing to a higher mortality rate among bees.While Dynamic Lifter has a poultry manure base and other added ingredients, Blood & Bone is 65% meat meal and contains cow manure. Fish, Blood and Bone fertiliser is an organic-based general purpose plant food which provides the major nutrients required for strong and healthy growth. Blood Fish and Bone Fertiliser Powder is a balanced organically based fertiliser in powder form. The nitrogen in Fish, Blood and Bone encourages strong growth and healthy rich green foliage, whilst the slow release of phosphate promotes vigorous root growth. The added potash promotes flower colour and improves ripening of fruit and vegetables. Ideal for all round use - Shrubs, Vegetables, Root crops and Herbaceous plants. It can be added to planting holes for most plants and is really useful when planting bulbs in the autumn as it encourages root growth which helps the plant to take up essential nutrients. It also contains nitrogen, which encourages plants to grow strong and promotes lush green foliage.
