The first biostimulant based on the fermentation of human urine
Efficient, Affordable, Eco-friendly
Fermenting human urine: why ?
Low NPK content
per liter: 9g of N / 2g of P / 2,7g of K
17 000 L/ha
to account for 35kg of phosphorus
bacteria and micronutrients
to solubilize 35kg of phosphorus in soil
A root biostimulant to secure crop emergence & early development, and improve the efficiency of the use of soil nutrients.
The Lactopi Start is based on the fermentation of human urine with the bacterial strain Lactobacillus paracasei. Isolated from soil in the South-West of France, this rhizobacterium has 3 interesting properties to secure early-stage vegetative growth, increase the efficiency of fertilizers, and improve plant tolerance to abiotic stresses.
Solubilization of soil phosphorus
Stimulation of root growth
for enhanced uptake of water and nutrients within the rhizosphere
Stimulation of mycorrhization
A safe & eco-friendly biostimulant
approved for use in organic agriculture
Toopi Organics’ filtration and fermentation process eliminates 100% of pathogens and up to 90% of micropollutants, ensuring a sanitized, stable product, safe for users and the environment.

In France (approval by ANSES n°1220824): Application before or at sowing : do not apply on crops whose consumable parts are in contact with the ground. Use for green spaces not authorized. In Belgium (M735.X waiver) : Lactopi Start is authorized on all crops at all growth stages, except for vegetables and fruits eaten raw, as well as herbs and fodder, where only sowing/on-sowing application is authorized.
>40 agronomic trials performed in France and Belgium
Secure rooting & early growth
The Lactopi Start, in addition to standard fertilization, stimulates rooting. Beet trial in Belgium with the SCAM, harvest to come in 2023.
Le Lactopi Start, en complément d’un itinéraire classique, stimule de système racinaire. Essai Maïs grain réalisé en Belgique avec la SCAM, 4 parcelles différentes, récolte 2023.
The Lactopi Start significantly increases the development of mycorrhizae. Maize trial in Belgium in 2022 with Etienne Allard, farmer.
The Lactopi Start, in addition to standard starter fertilizer, improves yield. Soy trial in France (64), in 2020 with Astria.
Reduce fertilizer use & expenses
Lactopi Start maintains yield while cutting the use of starter fertilizer by 50%. Irrigated maize trial in France (40), in 2021 with Astria.
An affordable alternative to inorganic fertilizers
Easy to use
Dilution and application (broadcast or in-furrow spraying), at sowing up to pre-emergence, planting or at the base for perennials.
12 liters of water saved for each liter of product. Less fertilizers, to reduce your costs and carbon footprint.

Lactopi Start I Urine-Based Biostimulant I Urine fermentation I Fertilizer replacement
Lactopi Start is a root biostimulant derived from the fermentation of human urine with a bacterial strain naturally present in the soil. Although urine contains NPK, Lactopi Start is not a urine-based fertilizer. It is a microbial product that can complement or partially replace fertilizers. It contains phosphate-solubilizing bacteria. Several trials have shown that Lactopi Start can replace up to 50% of phosphate-base or starter fertilizers (DAP for instance). Produced in France, Lactopi Start is approved for use in organic farming in all the European countries in which it was approved.
