The summary

Pure marine guano, 14% nitrogen and 9% phosphoric anhydride, for the vegetable garden and the orchard

Agro Sens seabird guano is a pure, unprocessed fertiliser, usable in organic farming, with an analysis of 14% nitrogen, 9% P2O5 and 2% K2O. Its high nitrogen content makes it a growth fertiliser for the vegetable garden, at 50 to 100 g per square metre, from March to October.

This guano is a deposit left by seabirds, pure and unprocessed. Its formulation is that of a growth fertiliser: 14% total nitrogen, 9% P2O5 and 2% K2O, which puts nitrogen well in the lead. This is why it is used at the start of your crops, when the plant is building its leaves and roots before producing flowers and fruit. It can be used in organic farming.

A soil fertiliser, not for water

At 14% nitrogen, this guano is for spreading on a vegetable bed, never in a system that feeds crops. In an aquaponic system, the nitrogen already comes from the fish, and adding more simply doubles up a source that is already there. The nitrogen cycle in aquaponics explains where this nitrogen comes from and what converts it. If you are feeding plants in water, choose the mineral supplements formulated for a nutrient solution instead.

🏡 Doses, surface by surface

The dose is worked out in grams per square metre, and it varies according to what is growing on the surface. To measure without scales, remember that a closed handful weighs about 40 g: two handfuls therefore make up the average dose for one square metre of vegetable garden. At these doses, a 1 kg bag feeds 10 to 20 m² of beds, and a 4 kg bag 40 to 80 m², which lets you choose the pack size according to the area you actually grow.

In the vegetable garden

Allow 50 to 100 g per square metre of cultivated bed, leafy salads and vegetables included.

In flower beds

Allow 100 g per square metre of perennial flower bed.

On lawns

Spread 80 g per square metre after the first mowing of spring.

🌱 Spread, rake in, water

When planting, mix the dose into the soil that fills the hole back in, so that the guano is not in direct contact with the roots. For maintenance, spread it on the surface around your plants, work it in with light raking, then water generously. This raking brings the granules into contact with moist soil, where the roots come to draw nutrients, whereas a fertiliser left dry on the surface is not absorbed. On dry soil, therefore, water first, then spread.

On poor soil, or for hungry crops, split the application into two over the season rather than giving it all in spring. Take a 10 m² vegetable plot: at the high dose it receives 1 kg over the year, that is roughly 500 g in April and 500 g in June, which works out at a generous handful and a quarter per square metre each time. That way you stay within the dose without ever doubling it, and the nitrogen is available just when your plants are building their foliage.

🗓️ From March to October

The period of use covers the whole growing season, from March to October. Give 50 to 100 g to a shrub depending on its size, and up to 200 g to a mature tree. Outside this window, your plants absorb little, and the nitrogen applied risks being washed away by winter rain before it has been used. As nitrogen is the dominant element here, plan for a potash supplement for fruiting crops: a potash and magnesium fertiliser takes over at flowering, when the plant's needs shift towards the fruit.

Three fertilisers, three different deficiencies to make up

This guano is the one that supplies nitrogen. The other two contain none at all.

A pale plant, or leaves turning yellow between the veins A plant that is pale all over is most often short of nitrogen. Older leaves that turn yellow between their veins point instead to a magnesium deficiency.
