SF Almácigos
Lima
SF Almácigos, a plant nursery in Peru, struggled with high soil salinity, which affected crop yields and plant health. Initial methods used to address the issue, like Reverse Osmosis (RO), proved costly and unsustainable due to water scarcity and high energy consumption. In 2020, they implemented the AQUA4D system, which significantly reduced soil salinity as effectively as RO but with far greater efficiency.
Over an 80-day period, AQUA4D consumed 3,000 times less energy than RO, using just 1.78 kW/m. compared to RO’s 3,549 kW/m., while also preserving the water’s natural composition. This shift to AQUA4D allowed SF Almácigos to lower operating costs and reduce environmental impact, making it a more sustainable, cheaper and energy-efficient solution for long-term water and soil management.
Approximately 23% of the world’s cultivated land is impacted by salinity.1 While soil salinization occurs naturally in arid and semi-arid regions, human activities and climate change can worsen it, negatively impacting crops, pastures, and trees by disrupting nitrogen uptake, limiting growth, and preventing plants from reproducing. Particularly, poorly managed irrigation systems can increase salt concentrations in soils, while rising sea temperatures, unpredictable rainfall, and sea level rise contribute to seawater seeping into freshwater sources. This worsens soil salinity, threatening agricultural productivity. This problem is especially pronounced in coastal areas, where the excessive accumulation of soluble salts can be damaging for arable lands.2
In Peru, this issue is significant, with around 300,000 hectares of irrigated land affected by salinization, half of which suffer severe salinity levels. Over 40% of Peru’s coastal agricultural areas face this challenge, making it crucial to address for sustaining agriculture and food production in the region.3
AQUA4D is the only technology which solves salinity by saving water in the process. In this sense, we can truly see this approach as a revolution for the management of salt in soils.

AQUA4D is a water-smart irrigation system that integrates into existing setups, enhancing efficiency and reducing soil salinity. Installed at the pump station, this machine uses low-energy technology to restructure water, improving nutrient absorption and flushing salts from soil. This boosts crop health and conserves water and energy, ideal for sustainable farming.
