Focus on pulses
Feeling the pulse in Argentina
This time our blog takes us to Argentina.
What crops would you associate with Argentina? Maize? Soybeans? Wheat?
Well, you’d be right about those. Together with sunflowers, these four crops account for more than 90% of the country’s total crop area. So it’s a reflection of the size of Argentina’s cropland – 35 million hectares, to be precise – that from that remaining 10 per cent, Argentina can also stake a claim to being one of the world’s leading producers and exporters of pulses.
In fact, Argentina enjoys the number five spot in the pulse production global rankings. With Argentinians themselves apparently indifferent about the pulse – annual domestic consumption is just 800g per capita – the country’s pulse growers focus their efforts on beans, peas and chickpeas for export to the Middle East, Latin America and the Mediterranean.
And while there’s evident diversity in Argentina’s pulse cropping, it’s the green pea that stands out as the obvious ‘hero’. Farmers have taken advantage of the country’s ideal growing conditions for peas: fertile soils, a favourable climate and (over the last season, at least) optimum rainfall to ensure a healthy, heavy crop. Added to that, its southern hemisphere location provides an ideal opportunity for counter-seasonal production.
In fact, according to an early-January prediction from the Global Pulse Confederation, Argentina is on track to deliver its largest-ever green pea crop this season, estimated at some 264,000 tonnes. That’s 108% above the five-year average and a massive 48% year-on-year increase.
It’s not just about meeting market demand, however. The green pea is a winter-spring crop for Argentinian farmers, easy-to-grow and profitable, that allows them to take a later crop of soybeans from the same field.
Unsurprisingly, Argentina’s pea growers also recognise the vital role that the green pea – as a legume – plays in sustainable agriculture. It’s these same attributes – improving soil biodiversity and health, easing crop rotations, improving chemical fertiliser use efficiency – that were recognised and highlighted by the UN’s World Pulse Day initiative, alongside its equally important role in global nutrition, food security, dietary diversity and efficiency.
FertiGlobal trials
It doesn’t take much to connect the dots. FertiGlobal’s own interests in sustainable agriculture, nutrient use efficiency, soil health and biodiversity clearly align well with the objectives of World Pulse Day, while our presence in Argentina is unsurprisingly focused on helping farmers ‘get more from less’ when it comes to their most important and most profitable crops.
Readers familiar with our blogs will recall how FertiGlobal’s head of technical development for the LATAM region, Josefina Mackern, enjoys nothing more than having ‘boots on the ground’ when it comes to technical development and application.
Enter our green pea trials in Argentina, conducted during the 2024 season. Josefina worked with FertiGlobal partner Synergy Agro to investigate how two of our technology platforms – Folistim and ACES – could improve yield and productivity in the green pea crop.
ACES
Our ACES Technology – Advanced Crop Eco Shield – combines natural nutrients that our R&D programme has proven to have beneficial effects on vital plant defence systems.
Galle, the product chosen for this trial, is a seed treatment designed to be applied in conjunction with, and to support, the inoculants commonly used in legume cultivation. Seed treatment allows these bioactive compounds to initiate these defence systems at an early stage in crop development, helping to ‘future proof’ each plant against subsequent pathogenic attack.
Five treatments (as table 1) and five replicates were employed, totalling 30 plots at the trial site in Heavy, Buenos Aires province.
Table 1

Observations were made of vegetative growth (plant survival and establishment, fresh shoot and root weight) and at harvest (hectolitre weight, thousand-kernel weight, and grain yield).
As Chart 1 reveals, the application to green peas of biostimulants as seed treatments is important for crop establishment and growth: Galle resulted in approximately 7% higher initial growth.

Several differences were observed in yield, consistent with the early growth observations. While treatment with the competitor 2 (Trichoderma) achieved the highest yield, Galle at 200ml per 100kg of pea seed was only marginally behind – representing a suitable biostimulant option when used in conjunction with inoculants.

Folistim
As with ACES, Folistim Technologies are formulated around natural compounds, in this case complexed with essential plant nutrients. The range is designed to biostimulate crops into optimising their use of nutrient elements so that they first prioritise vegetative growth and then support fruit quality and conservation.
In a second trial, the focus was on Rumis, a Folistim product that’s specifically formulated to favour development of roots and shoots. Its auxin-like effects promote earlier vegetative growth, especially in seedlings.
Also conducted in Heavy, this trial featured seven treatments made at two timings – first at flowering, then a second at pod formation.
Table 2

Assessments were made of vegetative growth (fresh shoot weight) and at harvest (pod length and grain yield). As Table 3 reveals, Rumis-treated plants displayed the heaviest fresh shoot weights.

When it came to yield, no major differences were observed in pod length but there was an apparent trend towards increased pod length when biostimulants were applied during pod formation.
As for yield (Chart 3), Rumis achieved the highest yield when it was applied at pod development (R4).

Although only an exploratory study, this trial nevertheless demonstrated the value of a biostimulant such as Rumis. Applied foliarly at 1l/ha, at full flowering and during pod development, it represents a highly suitable biostimulant to improve the green pea crop yield.
Conclusion
Argentina’s green pea cropped area is increasing rapidly. It’s not just because the end of the drought has restored fields to their optimum pulse-growing capacity, but also because in peas (and in pulses more generally) Argentina’s farmers have found a crop that can replace wheat in regions where it has lost profitability due to political, economic, and climatic conditions.
New crops demand new understandings and new techniques. We’re delighted to support Argentina’s growers in their adoption of crops like green peas.











But intensive farming has taken its inevitable toll – growers report depleted soils, and it’s recognised as an area on the ‘front line’ of climate change: altered rainfall patterns have increased the need for irrigation, leading to worries about groundwater depletion and desertification.
